In this paper, a decentralized overlapping static output feedback law is proposed to control a linear time-invariant (LTI) interconnected system. It is assumed that an overlapping information flow structure is given which determines which output measurements are available for any local control agent. Uncertain transmission delay is also considered in communication links among different subsystems...
This paper presents new stability conditions for Takagi-Sugeno (T-S) descriptors. Thanks to the descriptor redundancy, LMI based controller design of less conservatism are derived. These conditions are obtained using a fuzzy non quadratic lyapunov function (NQLF) approach with a non-parallel-distributed-compensation (non-PDC) control law. First, stabilization without constraints is considered for...
This paper considers the robust control of an active radial magnetic bearing system, having a homopolar, external rotor topology, which is used to support an annular fiber composite flywheel rim. A second-order dynamical compensator is used for control, its design being based on a linearized one-dimensional model which is treated as an interval system in order to cope with parameter uncertainties...
The paper considers the problem of synchronization for dynamical systems with unreliable communication links which are modeled as stochastic dropouts. A robust state feedback controller is designed such that the closed-loop system is stochastically stable in the mean square and preserves a guaranteed Hinfin performance. A numerical example is provided to show the effectiveness of the proposed results.
This paper presents a decentralized controller for a binary distillation column. The interactions between subsystems are considered as uncertainty. Then appropriate local Hinfin problems are defined such that by solving them and applying the designed controller to the system, closed-loop stability and diagonal dominance are guaranteed
