Decoupling with Classical Control Technique and Automatic Berthing Maneuver Control

Consistently Trained Artificial Neural Network for Automatic Ship Berthing Control

In this paper, consistently trained Artificial Neural Network controller for automatic ship berthing is discussed. Minimum time course changing manoeuvre is utilised to ensure such consistency and a new concept named ‘virtual window’ is introduced. Such consistent teaching data are then used to train two separate multi‐layered feed forward neural networks for com...

Decoupling Control

An Automatic Control System for Ship Harbour Manoeuvres Using Decoupling Control

This paper presents a new application of the Decoupling Control to automatically control large ships in harbour areas. A multi-term non-linear mathematical model is adopted to express ships’ manoeuvring motions. The method for designing the automatic control system is briefly described. Computer simulation results for a Very Large Crude Carriage (VLCC) on a simple berthing manoeuvre are given t...

An Introduction to Decoupling Control/MTT/July 1999 MULTIVARIABLE CONTROL: AN INTRODUCTION TO DECOUPLING CONTROL

Processes with only one output being controlled by a single manipulated variable are classified as single-input single-output (SISO) systems. Many processes, however, do not conform to such a simple control configuration. In the process industries for example, any unit operation capable of manufacturing or refining a product cannot do so with only a single control loop. In fact, each unit opera...

Optimal decentralized control design with disturbance decoupling

In this paper we present an input-output point of view for the problem of closed loop norm minimization of stable plants when a decentralized structure and a disturbance decoupling property are imposed on the controller. We show that this problem is convex and present approaches to its solution in the optimal t\ sense in the nontrivial case which is when the block off-diagonal terms of the plan...
