IWO-Fuzzy-Hybrid Control Strategy of Semi-Active Air Suspensions
摘要
Abstract
A novel magnetorheological damper with embedded permanent magnets( MREPM) was designed and inte-grated into vehicle suspension systems with air spring to restraining the vibration of vehicle induced by uneven pave-ment. Based on the principle of electromagnetism,the magnetic field and mechanics model of MREPM was estab-lished. Then,a 1/4 car model of semi-active suspension system with two degree of freedom was designed in MAT-LAB. A fuzzy controller which is optimized by invasive weed optimization ( IWO ) was built, namely, IWO-fuzzy hybrid control strategy. To validate the proposed control strategy in vehicle suspension,the dynamic simulation of ve-hicle system was carried out under C grade road random excitation and pulse excitation caused by convex block. The simulation result shows that the IWO-fuzzy control strategy can effectively improve the comprehensive performance of the semi-active suspension system. Moreover,through the shake table test,it is shown that the vibration acceleration of vehicle body and the dynamic deflection of suspension reduced by 25.87%,35.13% respectively.关键词
