Title:
LINEAR MOTOR MOTION CONTROL METHOD, APPARATUS AND DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2024/041042
Kind Code:
A1
Abstract:
The present invention relates to the technical field of linear motor motion control. Disclosed are a linear motor motion control method, apparatus and device, and a storage medium. The present invention involves: by using a state extension observer obtained by performing construction in advance on the basis of model parameters of a linear motor, performing state estimation according to a total control quantity and an actual displacement signal of the linear motor, so as to obtain observation signals; improving the estimation lag of a disturbance observation signal among the observation signals by using a phase advance controller; by using a model prediction controller obtained by performing construction in advance on the basis of a mathematical model of the linear motor, performing rolling optimization according to the observation signals, so as to obtain an optimal control quantity increment; and updating the total control quantity according to the improved disturbance observation signal and the optimal control quantity increment, and outputting a corresponding drive signal to a drive end of the linear motor according to the updated total control quantity. The present invention can quickly distinguish and attenuate a disturbance, thereby improving the motion control precision, response speed and anti-interference capability of a linear motor.
