Abstract:

A method of T immune fuzzy control was proposed. The T immune cell regulatory factor was introduced in the mathematical model of feedback control by applying the principle of immune T cell concentration regulation. And the nonlinear function of the fuzzy controller was used to approximate T cell regulatory factor. Compared with traditional PI control and immune feedback control, it can effectively suppress the effect of load disturbance on speed, electromagnetic torque output and current output. So it has excellent capability of resistance to systematic errors and speed following. Application on permanent magnet synchronous motor (PMSM) speed system shows the practicability of the proposed method.

Key words: permanent magnet synchronous motor, immune fuzzy control, immune feedback control, AC speed system
