Analysis of PMSM control performance based on the mathematical model and saturated parameters

In order to improve the analysis accuracy of PMSM control performance, this paper improves the mathematical model considering the SVPWM modulation index and the actual integrated voltage loss. And it presents an analytic method of control performance based on the saturated parameters of PMSM. By compared with the experimental results, we verified this kind of quantitative performance analysis method applying both Maximum Torque per Ampere (MTPA) strategy and voltage vector control in the flux weakening region has higher accuracy. Combined with the original analysis method it can be used to jointly designed for the motor performance, and optimize performance design.
