Study on stability for steering closed-loop system of remote-operated tracked vehicle

The stability for steering control closed-loop system of remote-operated tracked vehicle was studied for the purpose of developing steering control system. Through the analyze of steering closed-loop system, the model of steering closed-loop system was developed combined with a driver model based on compensation control, a model of remote control section, and a steering model of tracked vehicle. The effects of delay time, look ahead distance, control parameters on the handling stability of steering closed-loop system were simulated by using MATLAB. The steering control method with high dynamic response and variable control parameters was designed based on the delay time of remote control section. Simulation results show that the steering control method can enhance the stability of steering closed-loop system.
