摘要
常规的水轮发电机组维修吊装自动控制,主要采用估算驱动距离得出 自动控制结果,忽略了吊装运动副的自由度约束,导致自动控制结果稳定性不高.因此,提出水轮发电机组维修吊装自动控制算法研究.对维修吊装吊臂等关键零部件强度进行分析,在此基础上动力学分析吊装控制轨迹,基于分析结果为运动副添加自由度约束,分析控制反馈定位信息,循环迭代生成自动控制算法.实验结果表明,所提算法应用后得出的水轮发电机组维修吊装自动控制结果,表现出的平均稳定性为0.941,满足了维修吊装控制的实际需求.
Abstract
Conventional automatic control for maintenance and hoisting of hydraulic turbine generator units mainly us-es estimating the driving distance to obtain the automatic control results,ignoring the freedom constraints of the hoisting motion pair,resulting in low stability of the automatic control results.Therefore,a study on the automatic control algorithm for maintenance and hoisting of hydroelectric generator units is proposed.Analyze the strength of key components such as the maintenance lifting arm,dynamically analyze the lifting control trajectory,add degree of freedom constraints to the motion pair based on the analysis results,analyze the feedback positioning information of the control,and generate an automatic control algorithm through cyclic iteration.The experimental results show that the proposed algorithm has an average stability of 0.941 for the automatic control of maintenance and lifting of hy-draulic turbine generator units,which meets the actual needs of maintenance and lifting control.
