| 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. |
| Keywords: | double-loop current hysteresis loop coordinate transformation flux linkage |
