Abstract: In order to improve the anti-jamming capability and improve the dynamic performance, current
hysteresis and speed outer ring composed of induction motor double closed-loop control are used to further
improve the motor dynamic characteristics and anti-interference ability. When the load of 1. 5 s was changed from
15 N·m to 30 N·m, the speed remained constant at 1 400 r/ min, and can strengthen the flux linkage control.
We construct the multiple closed-loop control based on dynamic model of the asynchronous motor speed control
system. It is concluded that by using this control method the motor dynamic performance is better, and flux
linkage locus is more close to round.

Key words: current hysteresis loop, coordinate transformation, flux linkage, double-loop
