摘要
基于非线性系统理论,以相平面图为工具,研究电机的非线性补偿控制方法。以纯电动车转角控制系统为例,建立闭环非线性控制的模型,分析非线性环节对控制系统带来的不利影响,提出死区非线性补偿的控制方法。Matlab分析证明,该方法是合理、可行的。
The motor nonlinear compensation control method based on nonlinear system theory by using phase-plane technique is studied. A pure electric vehicle closed-loop nonlinear control model is established. The adverse influence caused by nonlinearity is analyzed and a control method of dead zone nonlinear compensation is proposed. Through Matlab analysis, the proposed method is proved to be reasonable and feasible.
