Orientation control system of three-phase AC asynchronous motor magnetic field

This article discusses the high and reliable single-chip microcomputer system composed of the programmable peripheral chip, dual-port static data memory and 16-bit microprocessor. Based on the characteristics of asynchronous motor, the principle of vector control transformation and PID parameters set in every link, the current model is used for the calculation. The system program memory and the preservation of a weak magnetic form are used to save CPU overhead. According to the law of quasi-optimum PWM, a kind of software is designed and prepared to realize the orientation intelligent control of AC asynchronous motor magnetic field.
