Three-Motor Synchronization Control Strategy Based on the New Speed Sensorless Active Disturbance Rejection Control

Abstract:

A new control method based on speed sensorless active disturbance rejection control (SS-ADRC) is proposed for overcoming the shortage of traditional PID control method in the application of the multi-motor synchronization system. By using the extended state observer (ESO), the internal and external disturbances in the system are compensated. According to the data driving principle, the formula of speed identification is inferred. Disturbances can be estimated online through ESO, and then speed value can also be identified by ESO. The simulation results show: the control system have strong decoupling ability, accurate speed identification ability, and good dynamic performance.
