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 ...
Cluster space linear parameter varying control of robot formations
(Institute of Electrical and Electronics Engineers, 2018)
Within the Cluster Space robot formation control scheme, a new approach is presented where a cascaded control scheme is proposed. On one hand, a simple secondary (inner) loop is used to control the formation’s velocity in ...
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 ...
Modeling and control of nonlinear systems using an Adaptive LAMDA approach
(Elsevier BV, 2020-01-01)
This paper presents a soft computing technique for modeling and control of nonlinear systems using the online learning criteria. In order to obtain an accurate modeling, and therefore a controller with good performance, a ...
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 ...
