汽车半主动悬架的模型参考滑模控制器设计与分析
Design and Analysis for Sliding Mode-following Controller of Semi-active Suspension System
摘要
Abstract
In order to improve the vehicle ride comfort and reduce the tire dynamic load,the 2-DOF mathematical reference model of semi-active suspension system with ideal sky-hook damping is established,and then the error dynamic system is built between the actual controlled system and the reference model system.The sliding mode surface is designed with pole assignment method.Moreover,the asymptotic stability condition of suspension system is derived based on the Lyapunov theory,and the system chattering is reduced with the index control law,which makes the actual controlled system can achieve the control effect of the ideal reference model and produce the asymptotically stable sliding motion.Finally,the sliding mode variable structure control model is built based on the ideal sky-hook damping model of the semi-active suspension.Numerical simulation verification is conducted and results indicate that the sliding mode control has a good control effect of the reference model system with good adaptability and robustness.关键词
