Motor-pump integrated machine combined control method and system
By constructing state feature vectors and dynamically weighted fused torque, the problem that the observer in the integrated motor-pump machine cannot distinguish between expected load and unknown disturbance is solved, achieving a balance between high dynamic response and stability, and strong parameter adaptability.

Abstract
The present application relates to the field of pump control, more particularly, the present application relates to a motor pump integrated machine combined control method and system, the method comprises: collecting the multi-source sensor data and equipment configuration parameters of the motor pump integrated machine, preprocessing the collected data, and constructing a state feature vector; state analysis and dynamic weighted compensation are carried out based on the state feature vector, the effective adjustment intensity coefficient and the disturbance separation factor are constructed, and the compensation torque considering the response speed and the inhibition capacity is generated; the compensation torque is superimposed to the speed loop output to generate the final motor torque instruction. The present application solves the control logic conflict caused by the traditional observer unable to distinguish the expected load and unknown disturbance, and takes into account the high dynamic response and high stability.
