摘　　要：钢丝绳卷扬提升式垂直升船机运行过程中,钢丝绳之间受力不平衡造成拉伸长度不均,导致船厢纵倾。为此,提出一种升船机液压动态调平控制方法。根据运动学原理建立液压的钢丝绳、液压缸及其活塞动力函数后,构建液压管道连通函数。运用比例放大装置、比例调速阀、液压缸与传感器搭建液压调平系统闭环传递函数。采用双输入三输出的动态矩阵、模糊理论设计控制装置,通过隶属度函数、加权平均算法求解最佳控制参数。根据此参数动态调整控制装置,实现液压平衡。实验结果表明,所提方法调平控制精度高,且控制用时短,能够有效保证升船机液压安全稳定。During the operation of the vertical ship lift with wire rope winch,the uneven tension length caused by the unbalanced force between the wire ropes leads to the longitudinal inclination of the ship compartment.Therefore,a hydraulic dynamic leveling control method for ship lift is proposed.According to the kinematics principle,the hydraulic wire rope,oil cylinder and its piston dynamic function are established,and the hydraulic pipeline connection function is constructed.The closed-loop transfer function of the hydraulic leveling system is built by using the proportional amplification device,proportional speed regulating valve,hydraulic cylinder and sensor.The control device is designed by using the dynamic matrix of two inputs and three outputs and fuzzy theory,and the optimal control parameters are solved by membership function and weighted average algorithm.According to this parameter,the control device is dynamically adjusted to achieve hydraulic balance.The experimental results show that the proposed method has high leveling control accuracy and short control time,and can effectively ensure the hydraulic safety and stability of the ship lift.
