Robust MPC suitable for closed-loop re-identification, based on probabilistic invariant sets
(Elsevier Science, 2018-08)
This work extends a recent set-based Model Predictive Control (MPC) scheme for closed loop re-identification that solves the potential conflict between the simultaneous persistent excitation of the system and the stabilization ...
Robust adaptive control using multiple models, switching and tuning
(Inst Engineering Technology-iet, 2011-12)
The supervisory control problem is analysed as an online robust design problem using switching to select the relevant models for designing the control law. The proposed supervisory control algorithm is based on the integration ...
Continuous performance monitoring of a closed-loop insulin delivery system using Bayesian Surprise
(QUALIS CAPES (UFSC), 2012-10)
The development of an artificial pancreas for the treatment of insulindependent diabetes is a big challenge for control theory. Many closed-loop algorithms have been widely evaluated for their ability to recreate, as closely ...
Multiple resonant controllers strategy to achieve fault ride-through and high performance output voltage in UPS applications
(The Institution of Engineering and Technology, 2018-11-13)
A control strategy to achieve fault ride-through capability and to provide high performance of the output voltage of a single-phase uninterruptible power supply (UPS) inverter is proposed in this study. This strategy ...
A new information theoretic test of the Markov property of block errors in fading channels
(Institute of Electrical and Electronics Engineers, 2005-03)
This paper introduces a new and effective information theoretic test of the accuracy of the Markov property of block errors in fading channels. We apply the test to verify the validity of a first-order Markov model for ...
A semi-closed loop microalgal biomass production-platform for ethanol from renewable sources of nitrogen and phosphorous
(Elsevier, 2019-03)
Production of microalgal biomass for feed and fuels demands unsustainable large amounts of fertilizers. The most broadly considered alternative sources of nutrients/fertilizer for microalgae are wastewater and internal ...
Artificial pancreas clinical trials: Moving towards closed-loop control using insulin-on-board constraints
(Elsevier Science, 2018-08)
Artificial pancreas (AP) systems for people with type 1 diabetes (T1DM) combine the use of a smart insulin pump with a Continuous Glucose Monitor (CGM) and a control algorithm to improve the regulation of glycaemia. Based ...
Neural network-based state estimation for a closed-loop control strategy applied to a fed-batch bioreactor
(Hindawi Publishing Corporation, 2017-07)
The lack of online information on some bioprocess variables and the presence of model and parametric uncertainties pose significant challenges to the design of efficient closed-loop control strategies. To address this ...
Fault diagnosis scheme for open-circuit faults in field-oriented control induction motor drives
(The Institution of Engineering and Technology, 2013-05)
In this study, a new model-based fault detection and isolation (FDI) strategy is proposed for field-oriented control (FOC) induction motor (IM) drives. Actuator faults are addressed, and specifically, single open-circuit ...
Vibrotactile Stimulation in the Upper-Arm for Restoring Individual Finger Sensations in Hand Prosthesis
(Institute of Biomedical Engineering, 2018-10)
The implementation of a sensory feedback system is particularly important in upper limb prosthesis to improve closed-loop control and prosthesis acceptance. Restoring the touch sensations of individual fingers becomes ...
