With the advancement of science and technology, practical systems are becoming more complex. Decentralised control has been recognised as a practical, feasible and powerful tool for application to large scale interconnected systems. In this paper, past and recent results relating to decentralised control of complex large scale interconnected systems are reviewed. Decentralised control based on ...

This paper briefly describes the results of a ten year, and still on-going, research program in decentralised sensing systems. This program covers both the theoretical development of data fusion methods appropriate to networks of decentralised sensors and the practical implementation of these in both civilian and military contexts. The methods employed for studying decentralised data fusion pro...

This paper will present the latest research endeavors into decentralised data fusion and control when using multiple uninhabited air vehicles. The paper will focus on the development of Decentralised Picture Compilation and Decentralised SLAM algorithms when applied to a 6DoF platform. The issues associated in the development of the algorithms and the conclusions drawn from such an endeavor wil...

In decentralized control it is known that the system can be stabilized only if the so-called fixed modes are all stable. If we have input constraints then (semi-)global stability requires all poles to be in the closed left half plane. This paper establishes that these two requirements are necessary and sufficient for stabilizability of a decentralized system with input saturation.

A simple and computationally efficient decentralised control design method is introduced for load-frequency control (LFC) in interconnected power systems. The method is based on the use of a reduced-order observer and a proportional-plus-integral controller in each area of the power system, and ensures zero static change in area-frequency and tie-line power. Some of the features of the decentra...

A structural decentralised control of discrete-event system (DES) is employed for a simulation study of a sequence control of cleaning-in-process of chemical batch plant. Due to the number of states of the whole plant model is too big, the whole plant has subdivided into smaller sizes and in the local level, the DES models for the local plant and local specifications are established. The condit...

This paper considers an algebraic approach for selection of the control structure aiming at facilitating the design of decentralised control schemes. This requires the selection of inputs, outputs, as well as their coupling that will allow the generic solvability of a variety of decentralised control problems. The approach is based on the use of necessary and sufficient conditions for generic a...

The paper aims at formulating an integrated approach for the selection of decentralized control structures using a number of structural criteria aiming at facilitating the design of decentralised control schemes. This requires the selection of decentralisation structure that will allow the generic solvability of a variety of decentralised control problems, such as pole assignment by decentralis...
