Research on acceleration slip regulation based on directly adaptive fuzzy control algorithm

Abstract

In view of vehicle's nonlinear characteristics and the insufficient adaptive ability of conventional fuzzy control, a directly adaptive fuzzy control algorithm is applied in Acceleration Slip Regulation (ASR). The principle of directly adaptive fuzzy control algorithm for ASR is analyzed, the initial value of the fuzzy based vector is given by the conventional fuzzy control, and the adaptive law of fuzzy parameters is also determined by Lyapunov function. Based on 7 DOF vehicle dynamics model, the simulation experiment of typical working condition in ASR has been done. Results show that, compared with the conventional fuzzy control, adaptive fuzzy controller is more smooth, fast and robustness.
