This paper presents a new optimized decentralized controller designmethod for solving the tracking and disturbance rejection problems for large-scale linear time-invariant systems, using only low-order decentralized controllers. To illustrate the type of results which can be obtained using the new optimized decentralized control design method, the control of a large flexible space structure is ...

It has recently been shown that a necessary and sufficient condition for the μstabilization of a linear time-invariant (LTI) retarded time-delay system by LTI decentralized finite-dimensional controllers is that the system should not have any μ-decentralized fixed modes with respect to decentralized static feedback. In the present work, we consider the stabilization of such systems by decentral...

This paper deals with the decentralized control of an interconnected system, where each subsystem has models of all other subsystems (subject to uncertainty). A decentralized controller is constructed based on a reference centralized controller. It is shown that when a priori knowledge of each subsystem about the other subsystems’ models is exact, then the decentralized closed-loop system can p...

Wireless structural sensing has attracted much research interest in recent years. With actuation functionality incorporated in the design of the wireless sensing nodes, a wireless feedback structural control system can be constructed. For wireless structural control systems that face challenges in communication range, latency, and reliability, decentralized system architectures can provide prom...

Decentralized Supply Chain Formation (SCF) appears as a highly intricate task because agents only possess local information, have limited knowledge about the capabilities of other agents, and prefer to preserve privacy. State-of-theart decentralized SCF approaches can either: (i) find Supply Chains (SC) of high value at the expense of high resources usage; or (ii) find SCs of low value with low...

Supervision based on place invariants (SBPI) is an efficient technique for the supervisory control of Petri nets. In this paper we propose extensions of the SBPI to a decentralized control setting. In our setting, a decentralized supervisor consists of local supervisors, each controlling and observing a part of the Petri net. We consider both versions of decentralized control, with communicatio...

A conceptual generalization of the Wald’s sequential probability ratio test (sprt) to a decentralized environment is presented. The local tests are chosen to be sprt’s, which quantize the temporally iid observations into three levels for transmission to the fusion detector. Spatial independence among the local observations is assumed. The fusion test is also an sprt. An analysis for the decentr...

In general, i t is not easy to design a decentralized controller for nonlinear interconnected systems. In this study, the stability of nonlinear interconnected systems is studied via fuzzy decentralized control method. First, the nonlinear interconnected systems are represented by an equivalent Takagi-Sugeno type fuzzy model. If the state variables are unavailable, a fuzzy observer-based state ...

In general, due to the interactions among subsystems, it is difficult to design an decentralized controller for nonlinear interconnected systems. In this study, the model reference tracking control problem of nonlinear interconnected systems is studied via decentralized fuzzy control method. First, the nonlinear interconnected system is represented by an equivalent Takagi–Sugeno type fuzzy mode...
