Abstract
In this chapter, the author presents the problems of design of the robust automated system for stabilization and control of platforms with aircraft observation equipment. The mathematical model of the triaxial stabilized platform is developed. The procedure of synthesis of robust stabilization system based on robust structural synthesis is represented. The above-mentioned procedure uses loop-shaping approach and method of the mixed sensitivity. The matrix weighting transfer functions are obtained. The optimization programs in MatLab are developed. The developed procedures are approved based on the results of simulation by means of the appropriate Simulink model. The obtained results can be useful for unmanned aerial vehicles and aircraft of special aviation, which are used for monitoring technical objects and aerial photography. The technical contributions are procedures of the robust controller design represented as the flowchart. The proposed approach is validated by application of the theoretical suppositions to the concrete example and appropriate simulation results.

Computer-Aided Design of Intelligent Control System of Stabilizing Platforms With Airborne Instrumentation
An automated system is called robust if it keeps stability and performance indices in some permissible range in conditions of disturbances influence without using adaptation methods. Stabilization System : A system, which keeps constant value of a controlled quantity under influence of changed disturbances, is called stabilization system.
