摘要
海上风电安装平台作为目前海洋风能资源开发的重要平台之一,其升降系统是风电安装平台的关键组成部分,直接影响着整个平台的工作效率和安全。以一个5600 t海上风电安装平台的液压升降系统为基础,分别对液压系统和同步控制器建立仿真模型,利用Simulink/AMESim两个仿真软件进行联合仿真,来研究在原系统基础上增加电液比例阀后的同步控制效果。分别设计PID控制器和模糊PID控制器,对液压升降系统的四组液压缸进行同步控制,对比研究两种控制器对液压升降系统的同步控制效果。通过联合仿真结果得出,对比原系统设定值为1 m时,常规PID控制器位移同步误差缩小了10.3 cm,模糊PID控制器缩小了12.1 cm。设定值为2.15 m时,常规PID控制器位移同步误差缩小了21.4 cm,模糊PID控制器缩小了26.1 cm。仿真试验证明模糊PID控制器有更加优异的控制性能,能够明显地缩小液压升降系统四组升降液压缸在提升过程中的位移同步误差。
Offshore wind power installation platform as one of the important platforms for the development of marine wind energy resources,offshore wind power installation platform lifting system is a key component of the wind power installation platform,which directly affects the working efficiency of the whole platform and platform safety.Based on the hydraulic lifting system of a 5600 t offshore wind power installation platform,a simulation model is established for the hydraulic system and the synchronous controller respectively,and Simulink/AMESim two simulation software are used to carry out a joint simulation to study the synchronous control effect after adding electro-hydraulic proportional valves on the basis of the original system.The PID controller and fuzzy PID controller are designed respectively to synchronise the four groups of hydraulic cylinders of the hydraulic lifting system,and the synchronous control effect of the two controllers on the hydraulic lifting system is compared and studied.Through the joint simulation results,compared with the original system set value of 1 m,the displacement synchronisation error of the conventional PID controller is reduced by 10.3 cm,and the fuzzy PID controller is reduced by 12.1 cm.when the set value is 2.15 m,the displacement synchronisation error of the conventional PID controller is reduced by 21.4 cm,and the fuzzy PID controller is reduced by 26.1 cm.The simulation test proves that the fuzzy PID controller has more excellent control performance,and can significantly reduce the displacement synchronisation error of the four groups of hydraulic cylinders in the lifting process of the hydraulic lifting system.
