Based on the principles of distributed control, centralized operation, graded management and integrated regulation, the system is distributed into management level, system control level, and device control level, which constitutes the distributed control.
Making PLC and DCS as the core technology and combining industrial control network and configuration software,the system implements concentrative management of whole plant and distributed control of each control station.
The state probability model and the control qualities the service probability evaluation model of the decentralization control random service system of the disappearance rule of an automatic control system are put forward. The service probability evaluation model will show the control qualities.
The system which is based on the technology of network and embedded system is programmed with object-oriented language and its database is SQL Server. It is consist of uniform control and decentralization control, which greatly saved the cost of development and maintenance.
This paper presents a feedback controller design technique for decentralized stabilization of interconnected systems with input-delay. By using the reduction method,all subsystems can be transferred to delay-free ones. Then,based on Lyapunov second method,a sufficient condition for the stability is derived in terms of linear matrix inequalities.
In this paper, the stability theorem for stochastic systems, the methods of random analysis and the Lyapunov functional method is employed to design the decentralized exponential stabilization controllers for a class of large scale retarded stochastic systems, a decentralized stabilization scheme with state feedback is given.
Pareto Effectiveness of Equilibria in Active Systems with the Distributed Control
Active systems with the distributed control (one active element and a few control centers) are considered.
Assessment of a Flexible Architecture for Distributed Control*
The method proposed has been applied on the distributed control architecture defined in the MUPAAC ESPRIT HPCN (Multi Processor Architecture for Automatic Control, High Performance Computer Networking of the European Commission).
