具有随机干扰的车辆座椅悬架系统的鲁棒H_∞控制
Robust H_∞ control for vehicle seat suspension systems with stochastic disturbance
摘要
Abstract
The paper proposes the design method of robust H∞ controller of vehicle seat suspension system.The dynamic model of seat suspension is developed,and the parameters uncertainties（mass,stiffness,damping） and stochastic vibration are introduced into the model system.Based on stochastic differential theory and Lyapunov functional,a semi-controller is designed,and the controller parameters are solved by linear matrix inequality（LMI） which guarantees H∞ performance index.The simulation results in time domain and frequency domain show that the controller designed for parameter uncertainties and stochastic vibration can attenuate the vertical acceleration of suspension system and improve riding comfort of human.关键词
