Abstract: For the current widely used adjacent cross-coupling control strategy, when the number of motors is large, the control structure is complex and the calculation is difficult which makes it hard to access the demand of simple and efficient high-precision synchronisation control. The adjacent cross coupling control structure is studied, and an iterative learning controller is designed. A new multi motor speed synchronisation control strategy is proposed, which reduces the complexity of the control structure. The simulation and experimental data prove that the control algorithm has strong robustness. Compared with the traditional adjacent cross-coupling control method, the synchronisation error of the system can be reduced by 78.17% and the tracking error can be reduced by 62.40%, which effectively improves the control accuracy of multi-motor synchronisation operation.

Keywords: permanent magnet synchronous motor; vector control; synchronous control; adjacent cross coupling control.
