Abstract: In this paper, a stochastic command filtering control method for permanent magnet synchronous motor with iron loss  was proposed to solve the problem of stochastic disturbance caused by permanent magnet synchronous motor (PMSM) driving process.The problem of “computational explosion” in traditional motor backstepping control was solved by using command filtering technology, and the filtering error was eliminated by the designed compensating signal. Neural network technology was used to approximate unknown nonlinear functions in the system. The stochastic Lyapunov function was selected and the stability of the system was analyzed. The simulation results show that the control method used in this paper can realize the fast tracking of the expected signal, effectively solve the stochastic disturbance problem of the system, and guarantee the stability of the system.
