Design and Implementation of Skyhook Controller for Semi-active Suspension Based on Obsener
摘要
Abstract
This paper establishes the dynamic model of the 1/4 vehicle semi-active suspension control system and designs the Kalman filter.In order to improve the control effectiveness of the observer,a sliding-mode observer is designed on the basis of the Kalman filter.According to the skyhook control algorithm,the controller based on the observer is established for the quarter-car semi-active suspension system.The simulation results show that,compared to the passive suspension,the ride comfort of the skyhook control based on Kalman filter and sliding-mode observer is improved greatly,but tires dynamic load is increased slightly.The designed Kalman filter can be well used to estimate the suspension's absolute speed and relative speed,but compared to Kalman filter,the sliding-mode observer can be used to estimate suspension states more accurately and its stability is better.The sliding-mode observer based on controller has better control effect.关键词
