Abstract: Focusing on optimizing the PID controller deficiencies about immutable control parameters, slow response speed and poor anti-interference performance, and solving the steady-state error made by conventional fuzzy logic control, an incremental fuzzy logic control method was introduced. By setting the changing rate of system output as the fuzzy controller’ s output, the incremental fuzzy rule base was designed by analyzing the principle of the incremental formula and
output features, which eliminated the system steady-state error while reducing the complexity of the control system. The simulation results of a FOC PMSM based on such incremental fuzzy logic control convinced that, compared with PID control and conventional fuzzy logic control, the PMSM with incremental fuzzy control had the advantages of fast dynamic response, small overshoot and strong anti-interference performance.
