Permanent magnet synchronous motor control method, system, device and equipment and storage medium

The invention discloses a permanent magnet synchronous motor control method, system, device and equipment and a storage medium, and the method comprises the steps: carrying out the observation of aperiodic disturbance caused by the parameter change of a motor through a pre-configured aperiodic disturbance observer, and obtaining a current aperiodic disturbance value; a pre-configured periodic disturbance observer is used for observing periodic harmonic disturbance caused by flux linkage saturation, inverter dead time and the like, and a current periodic disturbance value is obtained; on the basis, the non-periodic disturbance and the periodic disturbance of the permanent magnet synchronous motor are inhibited at the same time when the control quantity to be applied currently is determined, so that the interference of disturbance factors on the control process of the permanent magnet synchronous motor is reduced, and the control quantity with higher working condition adaptability is determined; therefore, the
