Description

technical field

[0001] The present invention relates to the field of ship control technology and manufacturing technology, in particular, to a design method for ship course trajectory tracking based on adaptive fuzzy optimal control. Background technique

[0002] Ship motion has the characteristics of large time lag, large inertia, and nonlinearity. Changes in speed and loading produce parameter perturbations in the control model. Factors such as changes in sailing conditions, interference from environmental parameters, and inaccurate measurements all make the ship's course Uncertainty arises in the control system. In response to the problems caused by these nonlinear uncertainties, intelligent algorithms are continuously applied to the field of ship course control, such as adaptive control, robust control, fuzzy adaptive control, iterative sliding mode control, and least parameter learning methods have been applied to ship course control system. However, in most of the cu...
