摘　　要：随着吊装吨位的大型化,工程上更多地采用双卷扬单吊钩的形式来对吊载系统提供足够的力矩。但由于液压系统的非线性、参数差异等原因会造成双卷扬系统产生同步误差。对闭式液压实验平台的液压系统与起升系统建立数学模型,采用常规PID和PID与CMAC(小脑神经网络)结合的方式分别进行控制。Simulink的仿真结果表明:PID与CMAC结合的控制方式的跟随性更好、控制精度更高。With the increasing of hoisting tonnage,more and more projects adopt the form of double winch single hook to provide sufficient torque to the hoisting system. However,due to the nonlinearity of the hydraulic system and the parameter difference,the synchronization error of the double winch system may be caused. In this paper,the mathematical model of the hydraulic system and the lifting system of the closed hydraulic experimental platform is established. Simulink simulation results show that the PID control mode combined with CMAC has better followability and higher control accuracy.
