Abstract
Permanent magnet synchronous motor (PMSM) is widely used in many fields due to its high-torque and high-power density. In this paper, a fixed-time integral sliding mode (FTISM) control is proposed, which enhances the position tracking ability and anti-interference ability of PMSM, thereby improving the control performance of the system. Firstly, the integrated terminal sliding mode controller is designed, which can ensure the system has excellent control precision and rapid convergence speed. The finite-time stability of the proposed FTISM scheme is demonstrated by using Lyapunov theory. Then, a PMSM algorithm test platform based on STM32G4 is designed, which can effectively run various control algorithms. Finally, the algorithm is simulated and verified in Simulink. The results indicate that the controller has high tracking performance and strong anti-interference ability, which can significantly reduce the position tracking error of the system and weaken the chattering phenomenon of the sliding mode control (SMC).
