Abstract

The invention discloses a motor current compensation control method and device, a motor, a storage medium and a processor, and the method comprises the steps: determining a target DC bus voltage of the motor according to a given rotating speed of the motor; obtaining the actual DC bus voltage of the motor; determining whether the actual DC bus voltage is smaller than the target DC bus voltage; if the actual direct-current bus voltage is smaller than the target direct-current bus voltage, calculating compensation current according to a voltage difference value between the target direct-current bus voltage and the actual direct-current bus voltage; and taking the sum of the given current and the compensation current of the motor as the operation current of the motor, and controlling the motor to operate according to the operation current. According to the scheme, the running reliability of the motor is improved by inhibiting the direct-current bus voltage fluctuation phenomenon of a permanent magnet synchronous motor control system without an electrolytic capacitor.

Description

technical field [0001] The invention belongs to the technical field of motors, in particular to a motor current compensation control method, device, motor, storage medium and processor, and in particular to a motor current compensation for high-frequency working conditions of a non-electrolytic capacitor permanent magnet synchronous motor speed control system Control method, device, motor, storage medium and processor. Background technique [0002] The permanent magnet synchronous motor is a motor with simple structure, low cost and high efficiency, which is widely used in industrial engineering fields such as aerospace, numerical control machine tools and electric vehicles. In related schemes, the permanent magnet synchronous motor drive system is a vector control system, and the vector control system uses two closed-loop feedback control loops of the speed loop and the current loop to control the drive voltage of the permanent magnet synchronous motor, and drives the perma...
