Title:
MOTOR VECTOR CONTROL METHOD AND APPARATUS, AND AIRCRAFT
Document Type and Number:
WIPO Patent Application WO/2018/019177
Kind Code:
A1
Abstract:
A motor vector control method and apparatus, and an aircraft. The method comprises the following steps: receiving a pulse position modulated (PPM) signal (S1); acquiring a first given voltage signal of a motor according to the PPM signal (S2); using a control method where a given d-axis current is 0 to obtain the voltage of the d axis of the motor (S3); and calculating the q-axis voltage of the motor at the next moment according to the first given voltage signal and the d-axis voltage of the motor, and performing vector control on the motor according to the d-axis voltage of the motor and the q-axis voltage of the motor at the next moment (S4). By means of the method, a direct given voltage manner is used to perform maximum torque control, so that torque pulsation generated by using the square wave control can be controlled, in order to reduce vibration and noise, and solve the problems of the loss of control and a strong jitter of a machine body caused by the use of speed closed-loop control.
