Design of Wind Pendulum Control System Based on Improved Genetic PID Algorithm

[摘要] Aiming at the attitude disturbance of the airborne ground tracking system and the problem of pointing stability under high-frequency vibration, and effectively utilizing the wind power outside the cabin, a new type of airborne ground tracking simulation platform-wind pendulum control system is designed, designed to TMS320F28335 For the control system of the main control chip, the controller adopts an improved genetic PID algorithm to realize the function of rapid braking and movement according to any desired trajectory. The simulation results show that, compared with the traditional PID algorithm, the improved genetic PID algorithm can better solve the problem of chattering, overshoot and non-fast convergence in a limited time in the system. At the same time, it has strong robustness to external disturbances, and can get the full physical simulation needs of airborne ground tracking systems.
