| description | The invention discloses a flexible control method for a permanent magnet synchronous motor. The method comprises the following steps: S1, establishing a dq axis mathematical model of the permanent magnet synchronous motor under a synchronous rotating coordinate system; s2, establishing a basic mathematical model of a general second-order linear active disturbance rejection controller; s3, obtaining a state equation based on the dq-axis mathematical model, introducing unknown disturbance according to the basic mathematical model, establishing a target current loop second-order linear active disturbance rejection controller, and obtaining a control current # imgabs0 #; and S4, generating a specific PWM control signal through an input signal # imgabs1 # obtained through Park inverse transformation, and inputting the specific PWM control signal to an inverter connected with the permanent magnet synchronous motor. Correspondingly, the invention further discloses a flexible control system for the permanent magnet s |
