This paper is concerned with the problem of robust l2-l∞ control for Networked Control systems. Dynamic feedback controller for Networked Control Systems with convex polyhedral uncertainties is given by the linear matrix inequality(LMI) method and cone complementary linear algorithm(CCLA). And the controller can guarantee a prescribed energy-to-peak disturbance attenuation level for all possible uncertainties...
This paper focuses on the problem of non-fragile static output feedback control for a class of T-S fuzzy bilinear systems (FBS). Based on the parallel distributed compensation (PDC) approach, the sufficient conditions are derived such that the closed-loop system is asymptotically stable in the presence of the additive controller gain perturbations. The stabilization conditions are further formulated...
This paper is concerned with the problem of robust control for a class of uncertain stochastic systems with discrete and distributed time-varying delays via dynamic output feedback control. The parameter uncertainties of system matrices are assumed to be norm-bounded. The purpose is to design a dynamic output feedback controller such that the closed-loop system is robustly stochastically stable for...
This paper considers a decentralized generalized H2 control problem for uncertain multi-channel descriptor systems with time-delays. The uncertainties are assumed to be time-invariant, norm-bounded, and exist in the system, time-delay and output matrices. Our interest is focused on dynamic output feedback. A sufficient condition for the uncertain multi-channel time-delay system to be admissible with...
For linear time-invariant normal controlled plant, under the assumption that controller and actuator adopt the method of event-time driven the system is a variable-sampling networked control system, and network-induced delay time is uncertain, it is less than or equals to a variable-sampling period. Basing on the dynamic output feedback the variable-sampling networked control system is modeled. Making...
Robust Hinfin control of the uncertain networked control systems is studied in this paper, and these systems have a general framework, which is uncertainty, delay, packet loss, disturbance, etc. Network-induced delays are modeled as Markov chains, dropout compensator between sensor and controller is presented and systems communicate data and signals via output feedback with state observer. Based on...
This paper presents robust decentralized power system stabilizer (PSS) design approaches for power system that can be expressed as minimizing a linear objective function under linear matrix inequality (LMI) in tandem with bilinear matrix inequality (BMI) constraints. In particular, the paper addresses two approaches with their practical implications for large power systems. These approaches are: i)...
Summary form only given. This work presents the fundamentals and the algorithm of a new methodology for the design of robust power system damping controllers. The methodology provides controllers capable of fulfilling various practical requirements of this problem, which could not be simultaneously satisfied by the majority of the proposed robust control approaches until now. The design procedure...
