电机驱动系统是一个由离散的控制信号驱动连续状态变量随时间演化的典型的混杂系统。针对传统的基于数学模型的建模方法都是研究逆变器中的开关元件开路等结构性变化,不能用于描述系统中的参数变化,本文建立逆变器和电机的混合逻辑动态模型,并运用Matlab/Simulink对系统中的R、L、Vdc等参数变化进行仿真分析,仿真结果表明该模型能很好地描述电机驱动系统参数的变化。

The motor drive system is a typical hybrid system which continuous state variable is driven by discrete control signal. Aiming at the problem that the traditional modeling method based on the mathematical model which can describe the power switch structural changes due to the open circuit faults occurred in the inverter and cannot describe the parameter changes of the element in the drive system, the simulation of motor drive system based on mixed logic dynamic model by Matlab/Simulink for parameters R, L and Vdc is presented. The simulation results show that the model can well describe the parameters change in the motor drive system.
