摘要
以波浪补偿反馈控制系统作为研究对象,分析了波浪速度补偿原理、正常吊放和波浪补偿测速度液压系统的工作原理,给出了恒张力的计算方法。推导了闭环系统的开环传递函数,采用了伪微分控制算法,计算了伪微分控制器的各个参数。最后,通过仿真表明,伪微分控制具有良好的动态响应,满足波浪补偿反馈控制系统要求,在其他控制领域也具有广阔的应用前景。
Wave compensation control system is taken as the research object, the principle of velocity compensation is analyzed, the principle of launching the goods in the normal state and measuring the velocity of wave compensation hydraulic system are also analyzed, the method to calculate constant tension is given, open loop transfer function in closed loop system is deduced, using pseudo-derivation feedback control related control parameter are deduced. Finally, as shown in the system simulation, pseudo-derivation feedback control has a good dynamic response, which can meet needs of wave compensation control system in full. It can also be used widely with a prospect future.
