Motor control method and device, motor, storage medium and processor

Abstract

The invention discloses a motor control method and device, a motor, a storage medium and a processor. The method comprises the steps of: using an FOC control strategy as a control strategy for controlling the motor under the condition that the motor is started; under the condition that the motor operates after being started, acquiring operation parameters of the motor; and according to the operation parameters of the motor, controlling the motor to switch from the FOC control strategy to use any one of a DTC control strategy, an FOC-DTC hybrid control strategy and a set magnetic field intensity control strategy, wherein a fuzzy PI controller is used in the process of controlling the switching to use any one of the DTC control strategy, the FOC-DTC hybrid control strategy and the set magnetic field intensity control strategy, and the switching of the operation parameters of the motor is controlled. According to the motor control method and device, two or more control strategies are switched for use in different control strategies of the motor (such as a permanent magnet synchronous motor), so that the robustness of the motor in the operation process can be improved.

Description

technical field [0001] The invention belongs to the technical field of motors, and in particular relates to a motor control method, device, motor, storage medium and processor, in particular to a method, device, and motor (such as a permanent magnet synchronous motor) automatic switching control strategy permanent magnet synchronous motor), storage media and processors. Background technique [0002] Permanent magnet synchronous motor (PMSM), due to its good performance, simple structure, fast response and high efficiency, is widely used in industry. Among the different control strategies of motors (such as permanent magnet synchronous motors), there are mainly field-oriented vector control (FOC) control strategies and direct torque control (DTC) control strategies, but they all have their own advantages and disadvantages. In the control strategy of the motor, the single use of any control strategy will affect the robustness of the motor during operation. [0003] The above...
