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 disadva...
