基于Matlab交流异步电机矢量控制系统的仿真建模

在分析交流异步电机数学模型的基础上,提出了交流异步电机控制系统仿真建模的新方法。在Matlab/Simulink中,建立独立的功能模块,如电机本体模块、矢量控制模块、速度控制模块、电流滞环控制模块等,再进行功能模块的有机整合,搭建交流异步电机控制系统的仿真模型。系统采用双闭环控制:速度环采用PI控制,电流环采用电流滞环控制。仿真结果证明了该方法的合理性、有效性,为实际电机控制系统的设计和调试提供了新的思路。

Modeling and Simulation of AC Asynchronism Motor Vector Control System Based on Matlab

Based on the mathematical model of AC asynchronism motor, a novel method for modeling and simulation of AC asynchronism motor control system in Matlab has been proposed. In Matlab/Simulink, the independent functional blocks, such as Moter model block, Vector control block, Speed controller block, and Hysteresis current controller block etc, have been modeled. By the organic combination of these blocks, the model of control system can be established easily. In the double loop of control system, a PI controller is adopted in the speed loop and a hyteresis current controller is adopted in the current loop. The reasonability and validity have been testified by the simulation results and this novel method offers a new thoughtway for designing and debugging actual motors.
