Servo Control System of NC Modifying Forming Grinding Wheel Based on Cross Coupling Theory

Abstract:

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.
