Synchronization Performance

In this paper, a cross-coupling synchronization controller is proposed to achieve a synchronous motion for high-precision positioning systems with uncertainties and disturbances, where an additional P controller is equipped to generate cross-coupling control action. Tuning procedure of the control parameters is also provided, so that improved tracking and synchronization performance can be obtained. The key to the success of the new design is to ensure that each motor tracks its desired trajectory while synchronizing motion with others. Experiments on a positioning system with two permanent-magnet linear motors demonstrate the effectiveness of the proposed control method.

Cross Coupling Control

This paper studies the synchronous control strategy which can meet certain dynamic performance and the closed loop robustness to external disturbance in servo system. This servo system has two same PMSMs which are used in a new CNC molding machine for forming grinding wheel. To achieve high-precision of the machine, we designed the hardware construction of the servo system. At the same time, this paper proposes a synchronization control scheme based on cross coupling control algorithms. The performance of the cross-coupled system is theoretically analyzed and simulated. It was proved that this synchronization control scheme has quick response, robustness and small dynamic process synchronization error, which could meet requirements of the high-precision synchronization control.
