Abstract

The 6000 m deep towed system is used in exploring and exploiting manganese which is deposited in the seabed over 5000 m underwater. In the paper, the real-time expert control system is employed to deal with the movement control problems of the 6000 m deep towed system. First, the dynamic motion process of the 6000 m deep towed system is analyzed. Then, the real-time expert control system is used in depth control of the 6000 m deep towed system. Finally, the results in depth control of the 6000 m deep towed system are discussed. Compared with a PID controller, the real-time expert control system gives significant robustness to disturbances and uncertainties
