【Abstract】 Based on the linear time-varying MIMO mathematic model of the brushless DC motor, this paper proposed a method to design a speed observer. The speed observer is linear identity state observer with simple algorithm and quick convergence, also its estimated precision is highly. At last, results of simulation demonstrated the method in this paper is correct and effective.更多还原
