摘　　要：通过对车辆电动助力转向系统结构及其动力特性的分析,建立了数学模型,针对系统传递函数有零点的特点,设计了一种有惯性滤波器串联的变结构控制器。仿真结果表明这种控制器有很好的控制效果,对参数的变化有较好的适应性。Based on analyzing electrical power steering system structure and its dynamical characteristics, the mathematical model is established. To eliminate the influence of uncertainties on the control, including the change of the system parameters, a variable structure mode controller with filter is designed according to the specialization of zero in the model transfer function. The simulation results show the controller is efficient and characterized with robustness in varying parameter of system.
