Abstract

The invention discloses a motor voltage injection method, electronic equipment and a storage medium. The motor voltage injection method comprises the following steps: acquiring an initial voltage set value and a magnetic pole position angle of a target motor; injecting a first voltage to a motor winding of the target motor based on the magnetic pole position angle and the initial voltage set value; collecting a historical feedback current and a current feedback current; determining a predicted feedback current according to the feedback current at the current moment and the historical feedback current; determining whether an overcurrent risk exists based on the predicted feedback current; if yes, reducing the initial voltage set value to obtain an adjusted voltage set value; and based on the magnetic pole position angle and the adjusted voltage set value, injecting a second voltage into the motor winding until it is determined that no overcurrent risk exists, and obtaining a target voltage set value for saturation model identification. The technical problem that the overcurrent risk is high in the inductance identification process in the prior art is solved.

Description

technical field [0001] The present application relates to the technical field of motor control, and in particular, to a motor voltage injection method, an electronic device and a storage medium. Background technique [0002] In the motor drive control system, the nonlinear change of motor parameters with different operating conditions caused by the characteristics of the motor itself greatly limits the optimal performance of the controller. In order to enhance the control performance and robustness of the controller, it is necessary to obtain precise motor parameters. In general motor drive control systems, the applicability and accuracy of the method for identifying the motor inductance parameters before the motor starts and runs, whether it is static identification or dynamic identification, need to be improved urgently. At this stage, whether it is the traditional motor inductance identification method or the innovative saturation model identification method, it is neces...
