【摘要】 目前,海上地震石油勘探系统中实际使用的拖缆自动定深器大多采用PID控制算法,以及采用压力传感器实时采集压力来进行深度闭环控制。本文在建立自动定深器状态反馈方程的基础上,设计了带全维状态观测器的状态反馈控制系统,并且对该系统进行了仿真分析。结果表明,利用本文所设计的控制器,该系统的动态特性明显优于经典控制器,可以为后续拖缆深度控制系统控制算法的优化提供参考。更多还原

【Abstract】 The depth controller of the marine seismic towed system mostly adopts the depth closed loop with PID control arithmetic currently,the state feedback control system based on the state feedback equations of the depth controller is designed in this paper,then the simulation is carried out.The result show that making use of the controller designed in this paper,the dynamic characteristic surpasses the classic controller obviously,the method of the towed cable depth control system provide a reference for the follow-up.更多还原
