Active-Synchronization Control System Used in DC Linear Motor

Aiming at the cutting for various kinds of material, in order to solve the problems that the present large band saw equipment at home is poor in the synchronization of the sawing feed and is lack of the dedicated NC system, the paper introduces the electro-hydraulic servo drive and digital control technologies, researches the synchronous servo drive and cutting force feedback control technologies, and develops the sawing machine’s control system based on the above technologies. The NC system has been applied in the CNC band saw equipment of the large Portal style. The saw frame uses the structure driven synchronously by the dual hydraulic cylinders in order to guarantee the accuracy of the feed motion. The control system driven by the electro-hydraulic servo synchronization detects the implementation of a two cylinders and does the displacement feedback to achieve the movement synchronization on both ends of the portal frame using the synchronous control strategy. That ensures the movement accuracy for the CNC band saw equipment of the large Portal style and improves the cutting accuracy and efficiency of the equipment.

Although the traditional synchronous control system for the virtual shaft has met the accuracy requirements of most products, it still can not fully meet the requirements, for the high precision, high synchronization control. This article proposed multi-motor synchronous control strategy based on the relative coupling control combined with virtual main spindle control, and built simulation platform by Matlab/Simulink and simulated the strategy. The simulation result shows that the synchronous control strategy mentioned in this article can overcome synchronization error brought by external disturbance and parameter variation. Moreover, it will better achieve the multi-motor synchronous control compared with the traditional virtual shaft synchronization scheme
