Fuzzy control strategy research about train’s lateral semi-active suspension
摘要
Abstract
To 17-DOF vehicle’s lateral semi-active suspension model, it is proposed that maximum and root mean square value of lateral acceleration are used to analyze lateral semi-active suspension fuzzy control strategy. To reduce lateral vibration and improve lateral stability, fuzzy control is used to adjust damping values in train’s semi-active suspension. So train’s lateral sus-pension is modeled by simulink. Direct and indirect method of fuzzy control strategy are designed. Simulation is also carried on. Simulation results show that lateral and synthetic acceleration of the front bogie is bigger than the back bogie through interaction between lateral and shaking acceleration;direct method is better than indirect method and passive suspension by analyzing power spectral density of acceleration at the same time.关键词
