【摘要】 减摇水舱试验台架是研究和设计减摇水舱的重要试验设备,准确模拟船舶在海浪中的运动是设计试验台架的关键,因此,采用电液伺服系统来模拟海浪力矩。针对高阶电液伺服系统,设计了基于Lyapunov稳定性理论的模型参考自适应控制器,并给出了理论分析、设计方法和仿真分析。仿真结果表明:这种自适应控制系统符合海浪力矩幅值和频率变化较快的设计要求,能够自动地适应海况的变化,具备较强的跟随性。更多还原

【Abstract】 The experimental platform of anti-rolling tank is a key equipment for the investigation of the anti-rolling tank and the accurate simulation of the ship’s moment in the sea waves,which plays an important role in the design of the ship anti-rolling test platform.In the present paper,electro-hydraulic moment servo is employed to simulate the moment of wave.For high-order electro-hydraulic servo system,based on the Lyapunov stable theory,the theoretical analysis method and the design result are presented.Simulation results show that the model reference adaptive control system can fulfill the requirements of rapid changes of wave amplitude and frequency torque,and the proposed system can be used under non-assumed sea condition,resulting a better tracking performance.更多还原
