Abstract
The conventional maximum torque per ampere (MTPA) operation usually neglects the derivative terms of interior permanent magnet synchronous motor (IPMSM) parameters, which significantly influences MTPA control accuracy. In this study, an MTPA control scheme that considers the derivative terms is developed, and a parameter identification strategy that considers the inverter to be non-ideal is developed for the calculation of the IPMSM parameters and derivative terms. In addition, the estimation accuracy of the motor parameters is further improved through the calibration of the nonlinear factors of the inverter. Finally, the effectiveness and accuracy of the proposed method is verified by simulation. This paper proposes practical methods for both inverter parameter estimation and accurate online MTPA control.
