New voltage distortion observer of PWM VSI for PMSM

A new online voltage distortion observation method against the motor parameter uncertainty of a permanent-magnet synchronous motor is proposed to estimate time-varying voltage distortion of a pulsewidth-modulation voltage-source inverter. This new estimation method is based on the model reference ad...
