Realization of Control Algorithm for Vehicle Optoelectronic Tracking Platform Based on Sliding Mode Control and Active Disturbance Rejection Control Optimized by Differential Evolution Algorithm

In order to improve the tracking ability of vehicle mounted photoelectric platform, and make its system has characteristics rapid response, small overshoot, high-precision position tracking, strong anti-interference good robustness, this paper, a joint active disturbance rejection control (ADRC) sliding mode (SMC) method is proposed, which can effectively equipment. Firstly, mathematical model DC motor analyzed, then based on linear extended state observer (LESO) third-order differentiator established as speed loop system. Finally, parameters nonlinear ADRC built system,s are optimized by improved differential evolution (DE) algorithm. The simulation results show that proposed algorithm better effect than PID algorithm, Robust algorithm; demonstrates performance controller DE parameter tuning experience. experimental illustrate ensure Optoelectronic Tracking equipment track target 3km away with 0.1 mrad accuracy.
