摘要
The critical section control method of a single decentralized sensorless PMSM according to an embodiment of the present invention uses a spatial vector modulation (SVPWM) control method for an alternating current motor, but uses a coordinate system represented by U, V, and W phases as a dq-axis orthogonal coordinate system. As a critical section control method for a motor controller that performs instantaneous control by expressing the physical quantity of the motor through two variables by converting to, the critical region of the motor in a change according to the angle of the effective voltage vector of the SVPWM control of the PMSM to the controller When the motor enters the critical area, SVPWM control for the motor is stopped, and when the motor escapes from the critical area, SVPWM control for the motor is resumed.
