Abstract

The invention discloses a permanent magnet synchronous motor control method based on improved sliding mode active disturbance rejection, and relates to the technical field of motor control. The method comprises the following steps: deducing a rotating speed loop state equation according to a mechanical motion equation of the permanent magnet synchronous motor; sliding mode variable structure control is introduced into the design of a speed active disturbance rejection controller, the nonlinear state error feedback control rate is improved, and the permanent magnet synchronous motor control method based on improved sliding mode active disturbance rejection is designed.

Description

technical field [0001] The invention relates to the field of motor control, in particular to a permanent magnet synchronous motor control method based on an improved sliding mode active disturbance rejection. Background technique [0002] The traditional permanent magnet synchronous motor speed regulation system often uses double closed-loop PID control, but because the output of the PID controller is difficult to efficiently adjust the system closed-loop, it can not meet the requirements of the control system; in view of the above problems, the present invention proposes a A permanent magnet synchronous motor control method based on improved sliding mode active disturbance rejection. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a new sliding mode control method for a six-phase permanent magnet synchronous motor, so as to solve the adverse effects of chattering generated in the traditional sliding mode operation of the motor and enha...
