Abstract:

In this thesis, a Linear Quadratic Gaussian Controller LQG is designed for a tail controlled surface-to-air missile model in order to meet design specifications. The mathematical model of the flexible missile is subject to uncertainties that may arise from unmodelled dynamics, parameter variation or linearization of nonlinear elements. Since these uncertainties are not taken into account in the LQG controller, microns Analysis is applied to the design in order to evaluate the Robust Performance, Robust Stability, and Nominal Performance of the system. Finally, a Linear Quadratic Gaussian controller is designed using Loop Transfer Recovery LQGLTR in order to improve the Robust Stability of the system. It is found that the Robust Stability of the design is improved, but as a consequence of losing nominal performance. The microns Analysis and Synthesis Toolbox and the Control Toolbox of MATLAB were used for the design, assembly, analysis and simulation of the missile flight control system.
