摘　　要：双马达同步驱动系统有质量轻,结构和负载对称等优点,在工程中得到较多运用。良好的同步控制方法是实现其功能及提高其性能的重要因素。建立双液压马达同步驱动系统数学模型,采用同步闭环控制,在位置反馈回路中设置PID调节器,基于NLPQL算法对PID参数进行整定优化,提高位置伺服精度。并利用双马达角位移差值均衡补偿等同方式对系统进行反馈校正,提高系统同步性能。System synchronized driven by doub- lemotor applied widely in engineering with the advantages of light weight, symmetric structure and load. Good synchronous control method was the key factor for implementing function and improving performance. This paper developed mathe- matical models of system synchronized driven by double hydraulic motor, used synchronous closed - up control to set PID regulator in position feedback loop, tuned and optimized PID parameters by NLPQL alzorithm for improving position servo accuracy, and made feedback compensation by double -motor angular displacement difference equilibeium compensation mode for improving synchro- nization performance of the system.
