This paper describes a slip frequency vector control system of inductionmotor using chip microcomputer MCS-51. A structure with parameter adaptive compensation is analysed and designed.
This paper deduces the relationship between power factor and slip angle frequency based on equivalent circuit of inductionmotor in stable state.
在此基础上讨论了直线感应电机转差频率控制方案的可行性，并给出了控制方案。
