    摘要:

    应用精确线性化方法研究了永磁同步电动机的非线性控制问题。根据精确线性化理论,设计了永磁同步电动机状态反馈线性化控制器和相对阶为1的多指标输入输出反馈线性化控制器。多指标非线性控制器选择全状态量线性组合形式为输出函数,根据系统特征根配置方法,整定了输出函数中各状态量的反馈系数。比较2种控制器仿真结果发现,多指标非线性控制器可以实现对电动机转速的有效控制,且控制器结构简单,设计方便,动静态性能良好。

    Abstract:

    The nonlinear control problems of permanent magnet synchronous motor were studied based on feedback linearization method. According to the feedback linearization theory, a state feedback linearization controller and multi-index input/output feedback linearization controller, which relative order is 1, were designed to control permanent magnet synchronous motor. The output function of multi-index nonlinear controller was selected as the linear combinations of state variables. The coefficients of state variables were determined by the method of characteristic roots configuration. The simulation results showed that the multi-index nonlinear controller could effectively control motor speed. The controller structure was simple, easy to be designed, and also had a good dynamic and static performance.
