Abstract

The invention provides an adaptive fuzzy optimal control method and system for an intelligent ship autopilot system, and belongs to the technical field of ship automatic control. The method aims at the intelligent ship autopilot system, and solves an output feedback control problem of the intelligent ship autopilot system through employing a fuzzy state observer, thereby effectively reducing the demands of a controller for the known state information of the change rate of the course angle of the autopilot system, and improving the course tracking speed and precision.

Description

technical field [0001] The invention relates to the technical field of ship automatic control, in particular to an adaptive fuzzy optimal control method and system for an intelligent ship autopilot system. Background technique [0002] Ship motion has the characteristics of large time lag, large inertia, and nonlinearity. Changes in speed and loading lead to parameter perturbation problems in the control model. Changes in sailing conditions, interference from environmental parameters, and inaccurate measurements all make ship heading control difficult. The system creates uncertainty. Faced with the problems caused by these nonlinear uncertainties, intelligent algorithms emerged as the times require, and have been continuously applied in the field of ship heading control, such as adaptive control, robust control, fuzzy adaptive control, iterative sliding mode control, and least parameter learning methods Wait. At present, most ship heading trajectory tracking designs adopt ...
