摘要: A sensorless speed control strategy for permanent magnet AC machines with nonsinusoidal EMF waveform is presented in this paper. First, a nonlinear observer proposed to estimate the as well rotor speed. Assuming that unknown, high gain time derivative of position linked flux, which needed estimation. Then, estimates are employed implementation torque minimum ripple. The performance proposal validated through simulation.
