ABSTRACT
The position sensorless control method based on unknown input observer was proposed aiming at the Interior Permanent Magnet Synchronous Motor (IPMSM) in this study. Due to PWM inverter output voltage of the IPMSM inconsistent with input reference voltage and in order to eliminate the influence of input voltage to rotor position, this study use sampling current as another state variable of the observer to build the unknown input observer, thereby estimate the rotor position at the high-speed. Simulation results show that the composite control has good dynamic characteristics in the full speed range.
