永磁同步电动机直接转矩控制在Simulink下的建模仿真

The modeling and simulation of permanent magnet synchronous motor direct torque control with Simulink

根据永磁同步电动机的数学模型,结合直接转矩控制理论,利用Simulink软件,对永磁同步电动机的直接转矩控制进行建模并仿真。控制系统加入比例、积分(PI)调节器,研究表明,合理设置PI调节器的比例系数和积分系数,能提高转速响应的速度,动态响应加快;同时稳态误差,即超调量也能限制在较小的范围。

According to the mathematical model of the PMSM and combine the direct torque control theory, brought out the simulation of the direct torque control of the PMSM after modeling it visa the Simulink software. PI regulator is put into the control system. The study has shown that if the PI parameters are set up rationally, the dynamic response speed is advanced,while the error of steady state can be limited in a narrow scope.
