Problems solved by technology
[0002] The energy storage system changes the kinetic energy of the system by increasing and decreasing the speed of the shafting to achieve energy storage. In order to enable the shafting to achieve the fastest speed, the existing technology uses magnetic suspension bearings. However, the system’s The magnetic bearing controller and the motor controller are independent of each other, so that the magnetic bearing system and the energy storage system only have less communication. Since each uses an independent controller, the number of electronic devices in the system is greatly increased, which not only increases the cost, but also The overall reliability of the system is reduced, and at the same time, there is a phenomenon of communication delay, which makes it impossible to realize real-time information sharing

The invention relates to the technical field of magnetic bearing and motor control and particularly relates to an integrated control device, system and method of a system based on a magnetic bearing and a motor. The method comprises steps of obtaining operation data of the motor and operation data of the magnetic bearing in real time; synchronously processing the operation data of the motor and the operation data of the magnetic bearing, and generating a control strategy according to the processing result; and outputting a control signal according to the control strategy to cooperatively control operation states of the motor and the magnetic bearing. The method is advantaged in that a traditional magnetic bearing controller and a motor controller are combined into a whole, data synchronization processing, unified control and real-time sharing of the operation data of the motor and the operation data of the magnetic bearing are realized, the response time of the system is reduced, the cost is greatly saved, the number of electronic devices is reduced, and reliability of the system is further improved.
