Abstract:

This paper designes a control system for gyro-stabilized platform based on the state compensating control theory. Advance compensator is used to restrict the frequency characteristic.Genetic algorithm is used to optimize the system parameters. MonteCarlo method is used to evaluate the robustness of the control system. Simulation results show that in the condition of external disturbance, parameters perturbation and coupling, the slopes of the performance curves obtained by using the control system designed have more than 43.7% in low frequency zone and less than 13.4% in high frequency zone characteristic as compared with classical controller, has less 0.2 s performance time, and has performance robustness of low disturbance sensitivity.

Key words: gyro-stabilized platform, active disturbance rejection control, Tornambe control, advance compensator, state compensating control
