摘要:
开发一套船模试验动力定位控制系统，系统控制器基于低通+陷通滤波算法、专家比例-积分-微分（Proportional Integral Differential，PID）控制算法、序列二次规划（Sequence Quadratic Programming，SQP）算法设计而成。将该系统应用于风浪中动力定位船模试验，测试船模运动、7个全回转推进器推力和角度响应，结果表明该控制系统具有合理性和有效性。
Abstract:
A dynamic positioning control system is developed for the ship model test. The controller of the system is designed based on low-pass, notch filtering algorithm, expert Proportional Integral Differential (PID) control algorithm and Sequence Quadratic Programming (SQP) algorithm. The system is used in the dynamic positioning ship model test in the wind and wave. The motions of the ship model as well as the propulsion force and angle responses of 7 rotary propellers are measured. The results show that the system is reasonable and effective.
