Abstract
This paper focuses on the matlab simulation of the asynchronous motor speed regulation , this paper analyzes the main control method , position and working principle of the induction motor slip frequency control , this paper analysis the dynamic model of asynchronous motor and further introduces the coordinate transfer and the basic principle of motor slip frequency vector control system. At the same time , the simulation work to prove its , according to analysis of the simulation results , the conclusions are as follows simply slip frequency control is always with poor load capacity , on the contrary the vector control applications can enhance the ability to regulate the motor of the torque and without pensation.
Key words:slip frequency,vector control,induction motor

1绪论

交流技术诞生于19世纪,但由于其性能无法与直流调速技术相比,所以过去的直流调速技术一直在电气传动领域中占统治地位。直到20
