摘要 在分析现有的各种助力控制策略的基础上,着重讨论了基于传统控制理论设计的电机控制策略与系统性能的关系,其中包括电流闭环PI控制器的参数设计及电流给定算法设计。最后,将这些基于简化线性系统模型的控制设计结果应用于电动助力转向系统的非线性仿真模型之中,仿真结果证明了这样的控制设计有效,在这种简单的控制结构下,系统的控制性能也能达到要求。 After analyzing different power steering systems, the control strategies for assist motor in an electric power steering system (EPS) are emphatically discussed based on traditional control theory, including the designs of current closed-loop PI controller and current set-point algorithm. The design parameters obtained based on simplified linear system model are applied to nonlinear EPS model. The simulation results show that the control strategies are feasible.
