AI Technical Summary

Technical Problem

In existing technologies, the doubly fed speed-regulating motors of high-pressure electric water pumps exhibit significant fluctuations during speed regulation, increasing energy consumption and mechanical wear, and affecting the motor's service life.

Method used

By acquiring the current and historical speed information of the target doubly-fed motor, the required speed information is generated to predict the speed, and a speed adjustment command is generated based on the transition speed information to achieve smooth speed adjustment.

Benefits of technology

It significantly improves the service life of the doubly-fed speed-regulating motor, reduces the impact and vibration during operation, optimizes the working efficiency of the high-pressure electric water pump, and enhances the operational stability.
