The synchronous control system is the essential device to the giant forging hydraulic press. Its synchronization control performance will directly determine product quality. The main causes of working cylinder asynchronism and its effect on synchronous control performance were analyzed. According to the practical problems of synchronous control application, an active synchronism control scheme was proposed based on multi-point driver.%同步控制系统是巨型模锻液压机上必备的关键装置,其同步控制性能的好坏将直接决定产品的质量.在分析主工作缸不同步的成因及对同步控制性能影响的基础上,根据巨型模锻液压机同步控制的实际应用问题,提出一种基于多点驱动的主动同步控制方案.
