Abstract During the operation of permanent magnet synchronous motor, traditional vector control method does not match regulator parameters with actual due to disturbance factors such as motor parameter perturbation and load change, resulting in decline performance. The research object robust is uncertain system, which has natural advantages for improving robustness system. Firstly, this paper i...

We propose a parametric model of the saturated Permanent-Magnet Synchronous Motor (PMSM) together with an estimation method of the magnetic parameters. The model is based on an energy function which simply encompasses the saturation effects. Injection of fast-varying pulsating voltages and measurements of the resulting current ripples then permit to identify the magnetic parameters by linear le...

This paper analyzed the effect of temperature on the permanent magnet flux and output torque. The major parameter which will impact the torque control accuracy of a surface mounted permanent magnet motor is the variation of the permanent magnet temperature. In addition, the temperature variation of the permanent magnet will also influence the maximum torque per ampere of the motor. To analyze t...
