Suboptimal control reconfiguration in switched multi-agent networked systems
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
In this work, the control recovery problem in a directed network of switched multi-agent systems is studied. A distributed cooperative control strategy is proposed which ensures that the agents reach a consensus while the ...
On design of suboptimal tracking controller for a class of nonlinear systems
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
In this paper, a new technique for solving the suboptimal tracking problem for a class of nonlinear dynamical systems based on the pseudo linearization is presented. Towards this end, an optimal tracking problem using a ...
Design of a hydraulic ankle-foot orthosis
(
IEEE Computer Society
, 2016 , Conference Paper)
This paper presents the design and simulation of an ankle-foot orthosis (AFO) to assist human walking. Design requirements were established based on a quantitative study of published data, simulations of human walking, and ...
Parameter Set-mapping using kernel-based PCA for linear parameter-varying systems
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
This paper proposes a method for reduction of scheduling dependency in linear parameter-varying (LPV) systems. In particular, both the dimension of the scheduling variable and the corresponding scheduling region are shrunk ...
Health monitoring and degradation prognostics in gas turbine engines using dynamic neural networks
(
American Society of Mechanical Engineers (ASME)
, 2015 , Conference Paper)
In this paper two artificially intelligent methodologies are proposed and developed for degradation prognosis and health monitoring of gas turbine engines. Our objective is to predict the degradation trends by studying ...
Undetectable Cyber Attacks on Communication Links in Multi-Agent Cyber-Physical Systems
(
Institute of Electrical and Electronics Engineers Inc.
, 2020 , Conference Paper)
The objective in this paper is to study and develop conditions for a network of multi-agent cyber-physical systems (MAS) where a malicious adversary can utilize vulnerabilities in order to ensure and maintain cyber attacks ...
Covert attack in load frequency control of power systems
(
Institute of Electrical and Electronics Engineers Inc.
, 2020 , Conference Paper)
The purpose of this work is to design a covert agent structure that can create a non-zero frequency deviation in the load frequency control (LFC) system and illustrate the necessity of a secure communication network for ...
Cyber Attack Detection for a Nonlinear Binary Crude Oil Distillation Column
(
Institute of Electrical and Electronics Engineers Inc.
, 2020 , Conference Paper)
Cyber security for Industrial Control Systems (ICS) is increasingly becoming an area of research as advance network technology continues to evolve providing extended connectivity between cyber world and control system ...
Mitigation and resiliency of multi-agent systems subject to malicious cyber attacks on communication links
(
Institute of Electrical and Electronics Engineers Inc.
, 2020 , Conference Paper)
This paper aims at investigating a novel type of cyber attack that is injected to multi-agent systems (MAS) having an underlying directed graph. The cyber attack, which is designated as the controllability attack, is ...
Rotor Flux-Oriented Control of Three-Phase Induction Motor Using Sliding Mode Controller and Rotor Flux Estimator
(
Springer Science and Business Media Deutschland GmbH
, 2021 , Conference Paper)
The work focuses on implementing rotor flux-oriented control (RFOC) for controlling the rotational speed and torque of a three-phase squirrel cage induction motor (IM). The speed controller has been implemented based on ...
