The Fuzzy Decoupling Control of the Electric Vehicle Steering and Speed Systems

Abstract:

Based on the electric vehicle steering and speed models, this paper discussed the control problems of the electric vehicle steering and speed systems. Firstly, the electric vehicle speed control system is designed using the fuzzy PID controller. Then the electric vehicle steering controller is a fuzzy controller. Due to the coupled effect of speed in the steering control system, designing a fuzzy decoupling controller, reducing the coupled effect of speed, in order to control the system of steering model and speed model independently, and to achieve the purpose of decoupling. Finally, the result of simulation proves that no matter how speed changes, steering control system still has good tracking performance with decoupling controller. The systemic robustness is much stronger and it also enhances the utility of the control system.
