摘要
从永磁同步电机(PMSM)的数学模型分析入手,得到了用于直接转矩控制(DTC)的电机转矩理论表达式。在此基础上就永磁同步电机直接转矩控制的实现作了深入解析,最后使用Matlab/Simulink对电机进行直接转矩控制仿真。仿真结果表明,直接转矩控制响应速度快,转矩波动较小。
This paper begins with analysing mathematical model of PMSM, torque equation for DTC is deduced. On the basis of analysis, an investigation on how to realize DTC in PMSM is carried out. At last, a simulationed DTC in PMSM is implemented using Matlab/Simulink, the results of the simulation indicate that the response of DTC is rapid and torque ripple small.
