Robust Parametrical Optimization of Discrete System for Stabilization of Apparatus of Land Moving Vehicles

This paper deals with creating the approach to the discrete system assigned used for stabilization observation equipment of land moving vehicles. The state-space mathematical description has been created. The system’s state and control in the vector form are shown. The analysis of discrete transformations has been carried out. The advantages of Tustin method are demonstrated. The possibilities of MATLAB for the implementation of discrete transformations are studied. Features of synthesis of the discrete stabilization system are described. Features of calculating the quality index based on norms of the transfer function of the stabilization system are given. The comparative analysis of different discretization methods is represented. The algorithm of the robust parametrical optimization is proposed. Simulation results including transient process and Bode diagram are given. The results in the form of transient processes prove the efficiency of the proposed approach. The obtained results can be useful for moving objects using observation apparatus of the wide class.
