Performance assessment of classical and fractional controllers for transient operation of gas turbine engines
(
Elsevier B.V.
, 2018 , Article)
The nonlinear behaviour of gas turbine engines has motivated the development of advanced controllers for ensuring their safe and reliable operation. In this paper, the problem of controller design for a two-shaft industrial ...
Event-triggered fault detection for discrete-time LPV systems with application to a laboratory tank system
(
John Wiley and Sons Ltd
, 2018 , Article)
This paper investigates a new event-triggered fault detection methodology for discrete-time dynamic systems characterized by linear parameter-varying models. An event-based linear parameter-varying observer is presented ...
Voltage control in distribution networks using current source converter STATCOM based on state feedback controller and Kalman filter
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Conference Paper)
In transmission and Medium-Voltage (MV) distribution systems, the voltage can be controlled by reactive power due to the high X/R ratio of the cables/overhead lines. Maintaining voltage within a fixed limit is critical to ...
Automatic blood glucose control for type 1 diabetes: A trade-off between postprandial hyperglycemia and hypoglycemia
(
Elsevier Ltd
, 2019 , Article)
Artificial pancreas (AP) systems perform automated insulin delivery to subjects with type 1 diabetes mellitus (T1DM). In this paper, a nonlinear suboptimal controller is designed to make a trade-off between the elimination ...
Fault-tolerant control of linear systems using adaptive virtual actuator
(
Taylor and Francis Ltd.
, 2019 , Article)
In this paper, design and development of fault-tolerant control (FTC) is investigated for linear systems subject to loss of effectiveness and time-varying additive actuator faults as well as an external disturbance using ...
Ensemble Kalman Filters for State Estimation and Prediction of Two-Time Scale Nonlinear Systems with Application to Gas Turbine Engines
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Article)
In this brief, we propose and develop estimation, prediction, and health monitoring methodologies for nonlinear systems by modeling the damage and degradation mechanism dynamics as 'slow' states that are augmented with the ...
An improved robust model predictive control for linear parameter-varying input-output models
(
John Wiley and Sons Ltd
, 2018 , Article)
This paper describes a new robust model predictive control (MPC) scheme to control the discrete-time linear parameter-varying input-output models subject to input and output constraints. Closed-loop asymptotic stability ...
Finite Frequency Fault Diagnosis for Heterogeneous Multi-agent LPV Systems
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Conference Paper)
This paper addresses the problem of distributed fault detection and isolation (FDI) observer design in finite frequency domain for a class of heterogeneous multi-agent linear parameter-varying (LPV) systems. For this ...
Optimal adaptive control of drug dosing using integral reinforcement learning
(
Elsevier Inc.
, 2019 , Article)
In this paper, a reinforcement learning (RL)-based optimal adaptive control approach is proposed for the continuous infusion of a sedative drug to maintain a required level of sedation. To illustrate the proposed method, ...
Event-Triggered Fault Detection for Networked Control Systems Subject to Packet Dropout
(
Wiley-Blackwell
, 2018 , Article)
This paper investigates the problem of event-triggered fault detection for discrete-time networked systems subject to packet dropout. The main aim of the proposed approach is to efficiently use the communication network ...
