Title:
MOTOR CONTROL METHOD AND APPARATUS AND TERMINAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/206027
Kind Code:
A1
Abstract:
A motor control method and apparatus and a terminal device. The motor control method comprises: determining a first current component of a first motor current under a two-phase stationary coordinate system α-β, and determining an electric angle compensation frequency according to the first current component and a first voltage component (S101); determining a voltage compensation coefficient according to the first current component, the first voltage component, and a preset disturbance signal (S102); and determining a first target voltage component according to a preset voltage coefficient, a preset electric angle frequency, the voltage compensation coefficient, and an electric angle compensation frequency (S103). The voltage compensation coefficient is determined by injecting the preset disturbance signal, the amplitude of the first target voltage component is optimized, and the efficiency of a system is improved. The motor control method has strong robustness to motor parameter variation, and can be simultaneously applied to high-speed and low-speed control of a salient pole synchronous motor and a non-salient pole synchronous motor.
