چکیده

This paper presents and discusses a fault-tolerant control model on a autonomous underwater vehicle (AUV) with six thrusters, using five degrees of freedom. Simulations were made when there are no faults and when faults occur in two of the horizontal thrusters. The kinematics and dynamics of the vehicle and the thrusters are explained and it is given an introduction of automatons and how they were used as base to build the vehicle’s supervisory control, created through the Stateflow tool from the software MATLAB. Keywords— auv, control, fault-tolerant, thruster Resumo— Este artigo apresenta e discute um modelo de controle tolerante a faltas em um véıculo subaquático autônomo (AUV) com seis propulsores, utilizando cinco graus de liberdade.

A cinemática e a dinâmica do véıculo e dos propulsores são explicadas e é dada uma introdução sobre autômatos e como eles foram utilizados como base para a construção do controle supervisório do véıculo, criado através da ferramenta Stateflow do software MATLAB.

Hybrid Adaptive Neural Network AUV controller design with Sliding Mode Robust Term

This work addresses an autonomous underwater vehicle (AUV) for applying nonlinear control which is capable of disturbance rejection via intelligent estimation of uncertainties. Adaptive radial basis function neural network (RBF NN) controller is proposed to approximate unknown nonlinear dynamics. The problem of designing an adaptive RBF NN controller was augmented with sliding mode robust term ...

Supervisory Recurrent Fuzzy Neural Network Guidance Law Design for Autonomous Underwater Vehicle

A guidance law, based on supervisory recurrent fuzzy neural network control (SRFNNC), is proposed for the autonomous underwater vehicle (AUV) guidance systems. This SRFNNC system is comprised of a recurrent fuzzy neural network (RFNN) controller and a supervisory controller. The RFNN controller is used to mimic an ideal controller and the supervisory controller is designed to compensate for the...

OPTIMIZED FUZZY CONTROL DESIGN OF AN AUTONOMOUS UNDERWATER VEHICLE

In this study, the roll, yaw and depth fuzzy control of an Au- tonomous Underwater Vehicle (AUV) are addressed. Yaw and roll angles are regulated only using their errors and rates, but due to the complexity of depth dynamic channel, additional pitch rate quantity is used to improve the depth loop performance. The discussed AUV has four aps at the rear of the vehicle as actuators. Two rule bases...

Hybrid Control Approach to Multi-AUV System in a Surveillance Mission

Surveillance missions for multiple autonomous underwater vehicle (AUV) system suggest the use of different modes of operation including organizing and keeping a predefined formation, avoiding obstacles, reaching static and tracking dynamic targets. While exploiting a leader-follower strategy to formation control and the vector Lyapunov function method to controller design, we use discrete-event...

Partial Observation in Distributed Supervisory Control of Discrete-Event Systems

Distributed supervisory control is a method to synthesize local controllers in discrete-eventsystems with a systematic observation of the plant. Some works were reported on extending this methodby which local controllers are constructed so that observation properties are preserved from monolithic todistributed supervisory control, in an up-down approach. In this paper, we find circumstances in ...
