基于变论域模糊控制的车辆半主动悬架控制方法
Control Method of Vehicle Semi Active Suspensions Based on Variable Universe Fuzzy Control
摘要
Abstract
A fuzzy control method was proposed based on variable universe fuzzy PID for vehicle semi-active suspension systems herein.The goals were to improve the ride comfort of vehicles under random road excitations.The fuzzy PID controller was combined with variable universe method to solve the problems that the fuzzy rules were blind and the online regulation time was too long.The simulations and experimental results show that,variable universe fuzzy PID control semi-active suspension systems in the body vertical vibration velocity and acceleration are reduced by 46.56％ and 29.21％ respectively in comparison with conventional PID controls,compared to the passive suspension systems they are reduced by 58.05％ and 49.74％ respectively.The vehicle semi-active suspension fuzzy control method has better effects on vehicle ride comfort.关键词
