Abstract:

This paper analyzes the immune network theory of immune system and presents a scheme for the adjustment of Proportional-Integral （PI） controller based on the immune network theory. The scheme is then applied to a direct torque-controlled speed-adjusting system of permanent magnet synchronous motor to overcome the variation of flux controller output and the low speed-adjusting accuracy due to the stator resistance variation. As compared with the conventional PI control and the PI control based on genetic algorithm, the proposed scheme is simpler in calculation and more accurate in control even in great stator resistance variation. The effectiveness of the proposed scheme is also verified by simulation.

Key words: immune system, immune network theory, permanent magnet synchronous motor, PI controller, direct torque control
