Ship heading intelligent control system and method thereof
By combining sliding mode control theory and nonlinear disturbance observer, the input and output domains of the fuzzy controller are adjusted in real time, which solves the problems of insufficient response speed, steady-state accuracy and anti-disturbance capability in existing heading control methods, and realizes efficient heading control of ships in complex sea conditions.

AI Technical Summary
Existing heading control methods struggle to balance response speed and steady-state accuracy, and lack sufficient disturbance rejection capabilities, failing to meet the demands of intelligent heading control for modern ships.
An adaptive law for the fuzzy rule consequent parameters is designed using sliding mode control theory. Combined with a nonlinear disturbance observer, the input and output domains of the fuzzy controller are adjusted in real time. The disturbances experienced by the ship are estimated through the nonlinear disturbance observer to form the final rudder angle command.
It achieves rapid response and high steady-state accuracy heading control under different operating conditions, enhances the system's robustness to model uncertainties and external disturbances, and improves the smoothness of ship handling and the service life of the steering gear system.
