Abstract
Aiming at the speed regulation system of permanent magnet synchronous motor (PMSM), the research and analysis of PMSM speed regulating system are made. Based on the finite time control technique, a finite time controller is designed in this paper. This design utilizes the error between the output of the speed and the reference speed, to be controlled by a finite time controller to obtain the q-axis current reference iq∗. And, based on the second-order model of speed control system, the reference speed can be tracked by the output speed in finite time. At the same time, the feasibility and validity of the verification is simulated by Matlab. The simulation results show that the proposed method guarantee that the output speed track the reference speed in finite time.
