摘要
为了模拟海洋钻井平台的升沉运动规律,设计并搭建了一套基于电液比例阀控马达的位置伺服系统,建立了系统数学模型,对控制算法进行了数值仿真与实验研究,采用逐步细化的分段PID方法实现了模糊PID算法。研究结果表明:带死区补偿的模糊PID算法稳定性好、控制精度高,实现了带载状况下高精度的升沉运动模拟,满足性能要求。
In order to simulate the heave movement of offshore drilling platform,the positional servo system which was realized on electro-hydraulic proportional valve-control motor was designed and built. Mathematical model was established. The control algorithm was studied by numerical simulation and experiment. Fuzzy PID algorithm was realized by using method of piecewise PID. The research results show that fuzzy PID algorithm with the function of dead band correction has good stability and high precision and realizes the heave movement simulation. The system meets the performance requirements.
