Road feel research of EPS based on fuzzy immune PID
基于模糊免疫PID的EPS路感研究*

In view of the existence of uncertainties such as model and disturbance signal in the EPS system. The goal was to obtain a good steering feeling and a small torque fluctuation for the driver. Biology immune system were characterized by their strong robustness and self-adaptability even when encountering strong disturbances and uncertain conditions, presented fuzzy immune adaptive PID control based on the immune feedback regulating of the process. Simulation results show that the controller has a strong anti-interference ability, fast response speed, meanwhile attenuate the noises and disturbance caused by model parameter uncertainty and the road impact.
