摘要
主动悬架是未来悬架的发展方向.将模型跟踪变结构控制理论应用于主动悬架系统的控制器设计中,研究了模型跟踪变结构控制系统的跟踪条件;用极点配置法设计了滑模切换函数,用指数趋近率改善滑模运动的动态品质.在1/4车辆动力学模型的基础上,利用matlab/simulink对该控制算法进行了计算机仿真,仿真结果表明:该控制器控制效果明显,能较好地改善车辆的乘坐舒适性.
Active-suspension represents the development trend of suspensions. Model-following variable structure control theory was applied to the design of controller for vehicle active-suspen- sion in this paper. The conditions were studied for using the theory and the parameters of the switching function were determined using the method of pole assignment. A rate exponent approach was used to obtain the control law. The efficacy of the scheme was investigated based on matlab simulation.
