对含分数阶阻尼器非线性悬架的PID控制研究
Research on PID Control of Nonlinear Suspension with Fractional Damper
摘要
Abstract
The PID control of the vehicle suspension system composed of the fractional order Bingham model and the nonlinear spring is studied,and the mathematical model of the second degree of freedom nonlinear suspension is established, and then ac￣cording to the requirements of the ride comfort the PID control er is designed. The simulation model of nonlinear suspension is estab￣lished in Matlab/simulink, the parameters of PID control er are defined,and the Oustaloup approximation algorithm is used to calcu￣late the fractional order calculus factor and the numerical simulation is realized. The results show that by comparison between this suspension and the passive suspension,the ride comfort with this suspension is significantly improved. This shows that with the frac￣tional dampers and the nonlinear spring,PID control er is used to effectively control the suspension al the same. It is of guiding sig￣nificance for the future study of the nonlinear suspension.关键词
