Decentralized stable factors and a parameterization of decentralized controllers
IEEE Transactions on Automatic Control, 1991Decentralized stable factors (DSF) are used to extend the stable factorization approach to the design of decentralized controllers. The DSF allow a parameterization of all the stabilizing decentralized controllers in the form of a Youla parameterization.

Limitations of Decentralized Control
Journal of Guidance, Control, and Dynamics, 1997Two types of limitations are discussed. The first ones are determined by specified requirements on acceptable complementary sensitivity and bounded gains in a fixed frequency region. Some necessary conditions for acceptable performance achieved by any decentralized control are shown.

Decentral control of a robot-swarm
Proceedings Autonomous Decentralized Systems, 2005. ISADS 2005., 2005In this paper, we present an approach to construct a universal architecture to control a team of autonomous robots. The suggested approach is robust against communication problems and robots' hardware failures. The system profits from its decentral architecture.

Decentralized control: An overview
Annual Reviews in Control, 2007Abstract The paper reviews the past and present results in the area of decentralized control of large-scale complex systems. An emphasis is laid on decentralization, decomposition, and robustness. These methodologies serve as effective tools to overcome specific difficulties arising in large-scale complex systems such as high dimensionality ...

Decentralized supervisory control with communicating controllers
IEEE Transactions on Automatic Control, 2000Summary: The decentralized control problem for discrete-event systems addressed in this paper is that of several communicating supervisory controllers, each with different information, working in concert to exactly achieve a given legal sublanguage of the uncontrolled system's language model. A novel information structure model is presented for dealing

Decentralized Control with Optimal Control Allocation
2007 IEEE International Conference on Networking, Sensing and Control, 2007Control allocation problem is the key of cooperation control systems and has attracted a lot of attention of researchers. This paper proposes a nonlinear control allocation framework to provide a common optimal solution for decentralized cooperation control systems. The framework includes the allocation controller and feedback control law.

Decentralized Controllability And Observability, And Decentralized Stabilization
Proceedings of the 1988 IEEE International Conference on Systems, Man, and Cybernetics, 2005In this paper the decentralized control of time-invariant linear multivariable systems is considered. The concept of decentralized controllable and observable space in decentralized control systems is introduced and the relationship between the decentralized controllable and observable space and decentralized stabilizability is studied, The sufficent ...

Decentralized Control and Decentralized Adaptive Control
2006Abstract : As systems become complex with many interconnected subsystems, decentralized control becomes essential. When certain parameters of the system are unknown, and/or when subsystems are not aware of the signals from other subsystems that affect their behavior, we need decentralized adaptive control.

Decentralized control of hybrid systems
Proceedings 5th International Symposium on Autonomous Decentralized Systems, 2002The key issue of a multi agent system is the decentralized control and optimization of a given global system which is normally of large scale. In this connection features like stability, controllability, and observability are important aspects. The paper deals with control structures of decentralized agent driven hybrid systems.

Sequential design of decentralized controllers
Automatica, 1994Abstract A procedure for sequential design of decentralized controllers for linear systems is presented. It is shown how to include a simple estimate of the effect of closing subsequent loops into the design problem for the loop which is to be closed.
