Title: Method and apparatus for controlling position sensorless motor
Inventor: IIJIMA TOMOKUNI
IPC: H02P21/18
Filed: 2001-10-02
Abstract: PROBLEM TO BE SOLVED: To provide a method and an apparatus for controlling a position sensorless motor wherein, when a rotor of a motor is at rest or rotating at low speed, noise is reduced as compared with conventional cases by a motor drive control and a signal- to-noise ratio in detection of a current in response to a signal for a rotor angle estimation is increased without delay in control as compared with conventional cases. SOLUTION: A current signal for a rotor angle estimation is superposed on a component in the γ-axis direction of a target current vector representing a target current of a stator winding. The period of the current signal for the rotor angle estimation is varied at even number times of a carrier period of a PWM and at random, and an amplitude is increased and decreased with an amplitude of the target current. Samples in an even number are obtained for each period from a component in the δ-axis direction of a current vector representing the detected current of the stator winding, and a discrete. Fourier integral is performed on these samples to obtain the amplitude in the δ-axis direction of a current in response to the current signal for rotor angle estimation.  The γ-axis direction is corrected so that a response current will be substantially zeroed in the δ-axis direction.
