MOTOR CONTROL METHOD, APPARATUS AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/284665
Kind Code:
A1
Abstract:
The present application discloses a motor control method, apparatus and system. The method comprises: generating first control quantity by using voltage control quantity and feedforward compensation quantity; determining an amplitude of a target voltage of a motor; using the first control quantity as control output quantity on the basis of a determination result that the amplitude of the target voltage is less than a set value; on the basis of a determination result that the amplitude of the target voltage is greater than the set value, determining whether signs of a d-axis component and a q-axis component in the first control quantity are identical; on the basis of the determination result that the signs of the d-axis component and the q-axis component in the first control quantity are identical, generating a q-axis component in the control output quantity by means of the q-axis component in the first control quantity and a q-axis component in the feedforward compensation quantity, and generating a d-axis component in the control output quantity by means of the set value and the q-axis component in the first control quantity; and generating the control output quantity by means of the set value and the voltage control quantity on the basis of the determination result that the signs of the d-axis component and the q-axis component in the first control quantity are not identical.
