Integrated Structure and Control Design for Servo System Based on Genetic Algorithm and Matlab

The integrated design was introduced about the pitching part of airborne radar servo system. The paper analyzed both the servo system model and the dynamic character of this system. Then the research about parameter optimization and simulation had been done by using the Matlab. The electromechanical coupling model and the optimization model were built up based on model of mechanism transmission system and electricity control system. The optimization model includes the integrated design of structure parameters and control parameters. The dynamics model of mechanism transmission system includes the nonlinearity of backlash. It considered the influence of parameters for dynamics property in structure of the mechanism transmission system. Furthermore, the model of electricity control system of the airborne radar servo system has three feedback-control loops. The method of integrated structure and control design was applied on the optimization model using Genetic Algorithm (GA). Simulation had been done based on Matlab/Simulik. Simulation results showed that the method of integrated structure and control design is very good. It is feasible and effective for airborne radar servo system. It proved the method used in the task is right and the practicability of Genetic Algorithm.
