摘要
海洋地震拖缆控制器系统是一种控制拖缆位置的系统。由于拖缆存在负浮力及容易受风、浪、流的干扰,如何精确控制水下深度是一个难题。针对系统具有非线性、时变不确定、强干扰、很难建立数学模型等特点,提出了模糊-PID控制的方法,建立了数学模型,设计了模糊-PID控制器,并用Matlab软件对其建模、仿真和优化。仿真结果表明,与传统PID控制相比,模糊-PID控制具有更高的稳态精度和更快的动态响应速度,能有效减小在勘探过程中由于拖缆位置的偏移而产生的误差,具有工程应用价值。
The marine seismic streamer controller system is a system which controls the position of towing cable.The towing cable has its own negative buoyancy and it is easily affected by the interference of wind,wave,flow,etc.So how to control the position of the towing cable precisely is the main problem.Aiming at the marine seismic streamer controller system with nonlinear,time varying uncertainties,strong disturbance and establishing mathematical models difficultly,and the traditional PID control has many disadvantages,the fuzzy-PID control method is proposed,the mathematical model is established,and fuzzy-PID controller is designed.MATLAB is used to modeling,simulate and optimize it.The simulation results show that compared with the traditional PID control,the fuzzy-PID control has higher steady state accuracy and faster dynamic response speed.It can reduce the error effectively due to the drag of the cable location offset in the exploration and it has the engineering value.
