摘要

In this paper, a kind of sensorless speed H control method for PMSM based on energy function is researched. In order to control the angular speed of motor rotator effectively, at first the Hamilton model of PMSM is shaped without considering disturbance, then the rotator speed can be controlled to reach the expected value. Considered disturbance, a H controller based on the Hamilton function is designed. A kind of observer is designed by the method of expansion plus feedback based on the Hamilton function and used to measure the angular speed of rotator, and the sensorless speed shaped plusing H control is achieved. The simulation result shows that the shaping plus H control based on the observer can estimate the angular speed of rotator accurately, restrain the voltage fluctuation of grid and control the angular speed of rotator effectively.
