Problems solved by technology

However, in practical engineering applications, the rudder angle change information of the ship heading system is mostly unknown, and the tracking error of the heading angle has performance requirements. The existing technology considers that the actual performance requirements of the ship heading control are less, and the use cost is high, which is not easy for engineering. accomplish

Abstract

The invention provides a fuzzy self-adaptive output feedback designation performance control method and system of an intelligent ship autopilot system, which belongs to the technical field of ship automatic control. The method uses error conversion technology and a fuzzy state observer for the intelligent ship autopilot system to solve the problem The output feedback of the intelligent ship autopilot system specifies the performance control problem, which effectively reduces the controller's need for the known state information of the course angle change rate of the autopilot system, and improves the course tracking speed and accuracy.

Description

Fuzzy adaptive output feedback designation performance control of an intelligent ship autopilot system manufacturing method and system technical field The present invention relates to ship automatic control technical field, relate in particular to a kind of fuzzy automatic control system of intelligent ship automatic steering system. Adaptive output feedback specifies a performance control method and system. Background technique Ship motion has the characteristics of large time delay, large inertia, non-linearity, etc. The changes of speed and loading lead to the control model. The problem of parameter perturbation, the change of navigation conditions, the interference of environmental parameters and the inaccuracy of measurement all make the ship heading control system created uncertainty. Faced with the problems caused by these nonlinear uncertainties, intelligent algorithms emerge as the times require and are constantly applied to The field of ship heading cont...
