This paper proposes a decentralized robust constrained cost fuzzy controller (DRCCFC) design for nonlinear descriptor interconnected systems (DIS) with uncertainties. The considered DIS is modeled using Takagi–Sugeno model (T-S FM) rules and strong interconnections. To derive sufficient stability conditions, the quadratic Lyapunov function (QLF) free-weighting (FWF) are defined. In contrast to ...

In Part I of this paper we propose a decentralized optimal frequency control of multi-area power system with operational constraints, where the tie-line powers remain unchanged in the steady state and the power mismatch is balanced within individual control areas. In Part II of the paper, we propose a distributed controller for optimal frequency control in the network power balance case, where ...

A navigation functions’ based methodology, established in our previous work for centralized multiple robot navigation, is extended to address the problem of decentralized navigation. In contrast to the centralized case, each agent plans its actions without knowing the destinations of the other agents. Asymptotic stability is guaranteed by the existence of a global Lyapunov function for the whol...

The decentralized navigation function methodology, established in our previous work for navigation of multiple holonomic agents with global sensing capabilities is extended to the case of local sensing capabilities. Each agent plans its actions without knowing the destinations of the others and the positions of those agents lying outside its sensing neighborhood. The stability properties of the...

This paper considers the dynamic output feedback controller design problem for decentralized GCS(guaranteed cost stabilization) of large-scale systems with time delays in subsystem interconnections and nonlinear uncertainties. Based on the Lyapunov method, an LMI (linear matrix inequality) convex optimization problem is formulated to find the controller which guarantees the asymptotic stability...

This paper considers the dynamic output feedback controller design problem for decentralized guaranteed cost stabilization (GCS) of large-scale systems with time delays in subsystem interconnections. Based on the Lyapunov method, a linear matrix inequality (LMI) convex optimization problem is formulated to find the controller which guarantees the asymptotic stability and minimizes the upper bou...

The objective of this paper is to propose an approach to decentralized robust stabilization with state-dependent supervisor for a class of nonlinear switched symmetric composite systems. The proposed methodology employs the structural properties of the system to construct a low order control design model as well as the multiple Lyapunov functions technique. Static output feedback gain matrices ...

In this paper, we introduce a new hyperchaotic complex T-system. This system has complex nonlinear behavior which we study its dynamical properties including invariance, equilibria and their stability, Lyapunov exponents, bifurcation, chaotic behavior and chaotic attractors as well as necessary conditions for this system to generate chaos. We discuss the synchronization with certain and uncerta...
