摘要
矢量控制技术严重依赖电机参数,传统电机参数测定方法需附加专业设备进行人工操作,易造成电机参数的测定误差,且在部分场合无法实施。为此分析给出了针对矢量控制感应电机参数的测定方法,该方法利用SVPWM技术控制逆变器,测定电机的定转子电阻、定转子漏感和互感参数。通过Matlab软件仿真和基于DSP的硬件控制平台验证了测定方法的可行性。
Vector control technology is heavily dependent on motor parameters. Traditional determination method of motor parameter needs specialized equipment for manual operation could easily lead to measure- ment error of motor parameters, and can not be implemented in some cases. Motor parameters identification algorithm was analyzed and obtained in this paper. This method used SVPWM technology to control inverter, in order to obtain the induction motor parameters. The simulation and experimental results demonstrated the feasibility of this method.
