Abstract
In this paper, a vector controller based on fuzzy sliding mode variable structure is designed for the influence of nonlinear and variable parameters on the performance of the system. On the basis of establishing the mathematical model of the asynchronous motor in the synchronous rotation orthogonal coordinate system oriented by the rotor flux, a sliding mode variable structure speed regulator using the exponential approach law is designed. The stability of the system is proved by the Lyapunov stability theorem, and the chattering of the system is reduced by the fuzzy algorithm. The simulation results show that compared with the traditional PI controller and the conventional equivalent sliding mode controller, the fuzzy sliding mode variable structure vector control system has better speed regulation performance, smaller torque ripple, and improves the robustness and anti-interference ability of the system.
