A Model Reference Self-Organizing Fuzzy Logic Controller for Auto Depth Control System of a Submersible Vehicle

Abstract

The self-organizing fuzzy logic controller(SOC) may often improperly modify the control rules when either the set-point or the disturbance changes. The problem leads the closed-loop system associated with SOC to the poor settling time and occasional large overshoot response. In order to overcome this problem, a model reference self-organizing fuzzy logic controller(MRSOC) is proposed in this paper. The usefulness of this controller is presented by the simulation results for auto depth control system of a submersible vehicle.
