DYNAMIC MODELING, GUIDANCE, AND CONTROL OF HOMING MISSILES ÖZKAN, Bülent Ph. D., Department of Mechanical Engineering Supervisor: Prof. Dr. M. Kemal ÖZGÖREN Co-Supervisor: Dr. Gökmen MAHMUTYAZICIOÐLU September 2005, 236 pages In this study, the dynamic modeling, guidance, and control of a missile with two relatively rotating parts are dealt with. The two parts of the missile are connected to each other by means of a roller bearing. In the first part of the study, the governing differential equations of motion of the mentioned missile are derived. Then, regarding the relative rotation between the bodies, the aerodynamic model of the missile is constructed by means of the Missile Datcom software available in TÜBÝTAK-SAGE. After obtaining the required aerodynamic stability derivatives using the generated aerodynamic data, the necessary transfer functions are determined based on the equations of motion of the missile. Next, the guidance laws that are considered in this study are formulated. Here, the Linear Homing Guidance and the Parabolic Homing Guidance laws are introduced as alternatives to the Proportional Navigation Guidance law. On this occasion, the spatial derivation of the Proportional Navigation Guidance law is also done. Afterwards, the roll, pitch and yaw autopilots are designed using the determined transfer functions. As the roll autopilot is constructed to regulate the roll angle of the front body of the missile which is the controlled part, the pitch and yaw autopilots are designed to realize the command signals generated by the guidance laws. The guidance commands are in the form of either the lateral acceleration components or the flight path angles of the missile. Then, the target kinematics is modeled for a typical surface target. As a complementary part of the work, the design of a target state estimator is made as a first order fading memory filter. Finally, the entire guidance and control system is built by integrating all the models mentioned abo.

Homing missiles have gained wide popularity in the field of guidance and control regarding the short and medium range purposes in recent years. In this study, the three-dimensional formulation of the Proportional Navigation Guidance (PNG) law is done. Another contribution of this study is the derivation of the Linear Homing Guidance (LHG) and the Parabolic Homing Guidance (PHG) laws. Then, all these three methods are implemented on both the considered missile model for the uncanted and canted tail wing configurations, and a generic single-body missile model. Also, the acceleration, rate and angular autopilots are designed in order to realize the guidance commands generated by these guidance laws on the considered missile models. Finally, the overall guidance and control models are constructed by integrating the obtained models and then numerous computer simulations are carried out to test the performance of the system in different scenarios.

The objective of this three year study is to develop robust and adaptive guidance and controls laws for homing missiles, mechanizable with near- future computer technology, which can satisfy system objectives in the presence of large uncertainties and nonlinearities. Over the past years, considerable progress has been made in resolving some of the fundamental issues in homing guidance. Of particular importance, new filter structures which were tailored to the passive homing engagement, and new target models and kinematic pseudo- measurements, which modified the new filter algorithm and induced a new adaptive homing guidance law, were developed. During the last three years in support of these important innovations, robust filters and control schemes which further enhance system performance were developed based upon a stochastic control problem known as the linear-exponential-Gaussian-problem and a related deterministic approach called the disturbance attenuation problem. Most important, emerging from this work is a new structure for adaptive control and a unifying framework for developing midcourse and terminal homing missile guidance schemes under uncertainty.

This book is concerned with dynamical systems under a large uncertainty, and uses a min-max approach to achieve worst-case design. The book consists of two parts. The first part deals with robust control. It begines by developing linear controls to achieve relative stability (pole clustering) under parameter uncertainty. Surprisingly, the largest robustness radius in the parameter space is sometimes discontinuous (fragile) with respect to the control parameters. Then, the book discusses the control of nonlinear uncertain systems under matching conditions. The second part uses differential games to develop optimal guidance for homing missiles against maneuvering targets. The target maneuver is bounded, but otherwise, arbitrary. Using miss distance as the cost, the book develops closed form guidance laws, as well as miss distance formulae. In this way, the control loop (autopilot) and the guidance loop are coupled. A parameter study reveals the basic difference between minimum phase (canards) and non minimum phase (tail control) missiles. It also shows the influence of the autopilot parameters on the miss distance.

Advanced Guidance Algorithms for Homing Missiles with Bearings Only Measurements

Advanced Guidance Algorithms for Homing Missiles with Bearings Only Measurements

Since this stochastic control problem assumes a nested information pattern, the filter structure can be developed independently of the guidance scheme. However, the guidance scheme is dependent on and affects filter performance.

Homing missile guidance is formulated as an optimal stochastic control problem where the special nonlinear structure of the missile-target engagement is exploited. Since this stochastic control problem assumes a nested information pattern, the filter structure can be developed independently of the guidance scheme. However, the guidance scheme is dependent on and affects filter performance. Significant progress is being made on both the estimation problem and the guidance problem. Investigation of the nonlinear estimators especially tailored to the homing missile problem has produced not only a good deal of insight but responsive and mechanizable schemes. Although these schemes are applicable to active sensors, our emphasis has been on the more difficult passive sensor case where only angles are available. Recently-developed schemes based on coordinate transformations and on a assumed probability density function perform well, but the modified-gain extended Kalman filter has been used as the basis of a stochastic adaptive flight control scheme. Two important current efforts in missile guidance with bearings-only information are in development of the guidance schemes that enhance an information measure by trajectory modulation and in target acceleration detection.

This book presents a comprehensive overview of the recent advances in the domain of optimal guidance, exploring the characteristics of various optimal guidance algorithms and their pros and cons. Optimal guidance is based on the concept of trajectory optimization, which minimizes the meaningful performance index while satisfying certain terminal constraints, and by properly designing the cost function the guidance command can serve as a desired pattern for a variety of mission objectives. The book allows readers to gain a deeper understanding of how optimal guidance law can be utilized to achieve different mission objectives for missiles and UAVs, and also explores the physical meaning and working principle of different new optimal guidance laws. In practice, this information is important in ensuring confidence in the performance and reliability of the guidance law when implementing it in a real-world system, especially in aerospace engineering where reliability is the first priority.

Excerpt: The Global Positioning System (GPS) is a space-based satellite navigation system that provides location and time information in all weather conditions, anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites. The system provides critical capabilities to military, civil and commercial users around the world. It is maintained by the United States government and is freely accessible to anyone with a GPS receiver. The GPS project was developed in 1973 to overcome the limitations of previous navigation systems, integrating ideas from several predecessors, including a number of classified engineering design studies from the 1960s. GPS was created and realized by the U.S. Department of Defense (DoD) and was originally run with 24 satellites. It became fully operational in 1994. Roger L. Easton is generally credited as its inventor. Advances in technology and new demands on the existing system have now led to efforts to modernize the GPS system and implement the next generation of GPS III satellites and Next Generation Operational Control System (OCX). Announcements from the Vice President and the White House in 1998 initiated these changes. In 2000, U.S. Congress authorized the modernization effort, GPS III. In addition to GPS, other...

Written by an expert with more than 30 years of experience, Modern Missile Guidance contains new analytical results, obtained by the author, that can be used for analysis and design of missile guidance and control systems. This book covers not just new methods nor is it merely a compilation of older methods, although it includes both. The book discusses, in a logical progression, with its clear elucidation of the guidance laws, the entire field from missile dynamics to modeling and testing missile guidance and control systems. In contrast to existing books that discuss very simple and often unrealistic guidance system models, this book presents missile guidance models that describe more precisely the dynamics of the missile flight control system, making analytical results more effective in practice. The analysis of missile guidance system models in the time-domain and in the frequency-domain allows the generation of different guidance laws that supplement each other. Taking modern, rigorous approach that leads to improved performance in missile guidance applications, the book examines new guidance laws, and corresponding algorithms for generating and testing these laws, and includes effective new software programs developed by the author. The author provides an innovative presentation of the theoretical aspects of modern missile guidance that quite possibly cannot be found in any other book. It delineates new ideas that, once crystallized, will significantly improve missile systems performance.
