Abstract

The invention discloses an induction motor control method, device and induction motor. The motor model calculation module is used to replace the PI regulator of the current loop in the vector control and the Park inverse conversion link, and the motor model calculation module is used to replace the traditional one in predictive control. Rolling optimization module and objective function calculation module. There is neither current closed-loop PI control nor complex rolling optimization in the whole control, which can reduce the debugging time, avoid the problems of large torque ripple and high sampling frequency, and make the control more direct and effective.

Description

technical field [0001] The present disclosure belongs to the technical field of induction motor control, and relates to a motor model calculation, an induction motor control method and a device thereof, and an induction motor, that is, a motor model calculation method, a motor model calculation module, an induction motor control method, An induction motor control device and an induction motor based on the control method. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] Model predictive control (Model Predictive Control, MPC) first appeared in the 1970s, was first applied to industrial process control, and has made great progress. Due to the high real-time requirements of the computing process, it was not realized in industrial process control until recent years and began to be widely used. In recent years, with the development of DSP and...
