基于切换模糊化的车辆速度滑模控制方法
Sliding Mode Control Method Based on Fuzzy Switch Function for Vehicle`s Speed
摘要
Abstract
Electric vehicle`s longitudinal control model is non-linear and vulnerable to external environment factors.This paper designes a sliding mode controller to improve the control system`s robustness.What`s more, this fuzzy controller reduces the inherent chattering of the sliding mode control method by adjusting the parameters of the switch function instantaneity.Compare with the common sliding mode control method, this paper`s controller is more stable, for this paper`s controller decreases the frequency of the control system`s input effectively.Simulation results show that system tracks the desired speed accurately and rapidly, while the system has strong robustness to parameter perturbation and external disturbances.关键词
