摘要
通过对永磁同步电机(PMSM)数学模型的分析得出了基于直接转矩控制(DTC)理论的转矩表达式,阐明了如何正确选择开关表来选择空间电压矢量控制逆变器,并通过MATLAB/SIMULINK建立仿真模型。仿真结果表明该方法具有较高的精度。
The torque expression based on direct torque control (DTC) is deduced through the analysison the mathematical model of permanent magnet synchronous motor (PMSM). It is explained how to cor-rectly select the switch table for space voltage vector to control inverter. A simulation model is built usingMATLAB/SIMULINK. The simulation results show that the method is with high accuracy.
