Study on hybrid-fuzzy control algorithm of wheel loader steer by wire system

This paper focuses on the wheel loader steer by wire system. For the reasons of the feature of the big variation range of steering resistance and the input flow, the serious non-linear, using the hybrid-fuzzy controller which combining the conventional PID and fuzzy controller together. This paper introduces the structure of steer by wire system, mathematical model of the system, the design process of the controller. The simulation results show that the hybrid-fuzzy controller has merits of quick response, little overshoot, no concussion. It can satisfy the requirement of actual steer by wire system.
