Abstract:To solve the unbalanced power output problem of dual-SRM synchronous driven shears, a power balance control system has been designed based on current cross-coupling algorithm and speed setting regulation control. The control system model has been established by using MATLAB/SIMULINK and simulation experiments have been accomplished. When a disturbance (its magnitude is 10% of the rated load) is applied on the drive-motor, compared with current system, the torque output difference of dual-SRM controlled by the designed system has been lowered by 7%, the maximum decrease of synchronous speed has been reduced by 3.5% and the transient time has been decreased by 1.5s. The results show that the designed power balance control system has improved both the synchronous accuracy of dual-SRM and the anti-disturbance capability of entire speed regulation system.
