Interior permanent magnet synchronous motor direct torque control simulation study

在永磁同步电机直接转矩控制系统的基础上,分析了内置式永磁同步电机的最大转矩电流比动态磁链控制。设计了基于SVPWM的磁链给定的直接转矩控制系统,通过电压空间矢量连续调节,减小了直接转矩中转矩脉动。在MATLAB/SIMULINK仿真模型下,对该系统进行仿真,验证控制系统的有效性。

In permanent magnet synchronous motor direct torque control system, on the basis of analysis of the interior the maximum torque per ampere of permanent magnet synchronous motor current dynamic flux linkage control. Design flux based on SVPWM given direct torque control system, through the voltage space vector of continuous adjustment, reduce the flux and torque ripple in direct torque. Under the MATLAB/SIMULINK simulation model, we simulate the system verify the validity of the control system.
