Trajectory Tracking Control of a DC Motor Exposed to a Replay-Attack

Advances in Science, Technology and Engineering Systems Journal, Volume 5, Issue 3, Page # 264–269, 2020; DOI: 10.25046/aj050334
Abstract:

This paper investigates the trajectory tracking control (TTC) problem of a networked control system (NCS) against a replay-attack. The impact of data packet dropout and communication delay on the wireless network are taken into account. A new mathematical representation of the NCS under network issues (packet dropout, delay, and replay-attack) is proposed, the resulting closed-loop…

Robust synchronization of nonfragile control of complex dynamical network with stochastic coupling and time-varying delays

Advances in Science, Technology and Engineering Systems Journal, Volume 4, Issue 2, Page # 8–16, 2019; DOI: 10.25046/aj040202
Abstract:

This paper explores the problem of robust synchronization of complex dynamical network with stochastic coupling and time-varying delays through the application of nonfragile control. A well defined Lyapunov Krasovskii functional is established and by employing the widely acknowledged extended Jensen’s integral inequality and the Bernoulli’s distribution sequences, the stochastic nature of network coupling is modeled…

Actuator Fault Reconstruction based Adaptive Polytopic Observer for a Class of Continuous-Time LPV Systems

Advances in Science, Technology and Engineering Systems Journal, Volume 3, Issue 1, Page # 443–450, 2018; DOI: 10.25046/aj030154
Abstract:

This paper is an extension of work originally presented in conference name. The goal is to propose new fault detection and fault isolation techniques for a polytypic linear parameter-varying system (LPV). In this work, an adaptive observer design is formulated for a given polyquadratic Lyapunov function. Subsequently, new sufficient conditions are given in terms of…

Decentralized Control Approaches of Large-Scale Interconnected Systems

Advances in Science, Technology and Engineering Systems Journal, Volume 3, Issue 1, Page # 394–403, 2018; DOI: 10.25046/aj030148
Abstract:

In this paper, we investigate the decentralized control problem for largescale interconnected systems. The synthesis of the decentralized controller consists in determining gains which ensure the stability of the global system. To calculate these gains, three approaches are presented. Our main contribution is to develop a new decentralized stabilization approach which the decentralized local gains…
