Background
In practical application, the stepping motor is an actuating element of a servo system, so that the design of the stepping motor is more focused on the aspects of accurate position positioning, larger torque generation and the like. In the design of the stator and the rotor, the stator and the rotor are all in a salient pole structure, small teeth are arranged on the poles, and a larger space harmonic exists in an air gap magnetic field, so that the torque pulsation and the rotation speed fluctuation of the motor are also larger, and noise is easily generated to cause oscillation. To solve this problem, many studies have been made by those skilled in the art.
For example, the application No. 200910110021.8 discloses a device and a method for suppressing the rotational oscillation of a rotor of a hybrid stepping motor. And the torque pulsation quantity is acquired and integrated, and the phase angle modulation quantity is obtained by multiplying the torque pulsation quantity by a corresponding coefficient to suppress the rotor oscillation. In the scheme, a band-pass filter is used for acquiring the torque pulsation, the frequency range of the torque pulsation is different along with the difference of voltage, current, motor type and load, the parameters of the band-pass filter need to be adjusted, the universality is poor, and the use is inconvenient.
In the method, a flux linkage observer is used for obtaining an estimated angle of a rotor, the estimated angle is differentiated to obtain speed, a high-pass filter is used for obtaining speed pulse vibration quantity, and the speed pulse vibration quantity is multiplied by a certain gain to obtain a given angle correction quantity. In the scheme, the angle is obtained by estimating the angle of the rotor, and the differential is carried out to obtain the rotating speed; applying differentiation amplifies the noise signal, affecting the operation of the system.
And the output voltage of the existing hybrid stepping motor is not effectively compensated, so that the output torque of the motor is not large enough.
