Abstract：In order to solve the problem of long response time of control based on linear sliding mode surface control,an en-hanced linear sliding mode surface is first designed to make the system state converge in the form of power-exponential after reach-ing the sliding mode surface,so as to shorten the convergence time after the system state reaches the sliding mode surface.Secondly,the existence condition of the sliding mode is improved to make the system state reach the sliding mode surface in limited time,so as to shorten the time ofthe system state approaching the sliding mode surface.Finally,the improved method is applied to the PMSM speed controller,and the simulation results are compared with the PI and linear sliding mode surface methods respectively.The re-sults show that the system response time of the improved method is obviously shortened.
