摘要
A slip frequency vector-controlled system is not robust because it needs accurate mathematical model of the motor and it traditionally uses the PID method. By applying regular fuzzy control, the system's robustness can be improved, but the steady-state precision is lowered. This paper introduces a self-adjusting fuzzy speed controller in a slip frequency vector-controlled system. It can not only enhance the robustness of the system, but also improve the steady-state precision and dynamic performance. A simulation example is also presented
