Optimal gain‐scheduling control of proton exchange membrane fuel cell: An LMI approach

IET Renewable Power Generation, 2022
Here, an optimal linear parameter varying (LPV) controller is developed for non‐linear proton exchange membrane fuel cell (PEMFC) systems. Two performance criteria are involved in the optimal controller, including the membrane pressure and the power of ...

Sliding Mode Control in Aerospace Applications: A Survey

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT Sliding mode control (SMC) enjoys robustness to matched and unmatched (in the case of minimum phase input‐output dynamics) bounded perturbations, and finite time convergence. Second‐order and higher‐order sliding mode control systems (2‐SMC/HOSMC) retain all the advantages of sliding mode control, but in addition can be applied to systems of ...

Outracing a National Level Model Racing Car Champion: A Hybrid Model‐Based Data‐Driven Approach

Journal of Field Robotics, EarlyView.
ABSTRACT This paper discusses lap time optimization, focusing on a single lap without considering opponents in autonomous racing. The paper presents a control and optimization architecture composed of a model‐based low level controller and a higher level iterative learning algorithm with the goal of obtaining the fastest qualifying lap in autonomous ...

Temporal shifts in antiretroviral therapy regimens and metabolic outcomes in people living with HIV: A systematic review and meta‐analysis

HIV Medicine, EarlyView.
Abstract Introduction Antiretroviral therapy (ART) for people living with HIV has led to dramatically reduced mortality and improved life expectancy. This achievement is accompanied by a higher risk for metabolic and other non‐communicable diseases. The role and contribution of various ART regimens to adverse metabolic outcomes are not fully understood.

HIV drug resistance and treatment success in the Republic of Congo: Implications for optimized treatment

HIV Medicine, EarlyView.
Abstract Objectives Increasing rates of HIV‐1 drug resistance (HIVDR) threaten the effectiveness of antiretroviral therapy (ART) programmes in sub‐Saharan Africa, particularly among children, adolescents and young adults, who face limited treatment options.

Impact of Carina Width on Re‐Ablation Rate of Atrial Fibrillation After Primary Cryoballoon‐Ablation

Journal of Cardiovascular Electrophysiology, EarlyView.
Right side carina width is associated with the incidence of reconnection of RPVs and re‐ablation. Increased left side carina width was associated with re‐ablation rate, but there was no association with reconnection of the LPVs. ABSTRACT Background Reconnection of the pulmonary veins (PVs) is the primary cause of atrial fibrillation (AF) episodes after

Robust linear parameter varying induction motor control with polytopic models [PDF]

Serbian Journal of Electrical Engineering, 2013
This paper deals with a robust controller for an induction motor which is represented as a linear parameter varying systems. To do so linear matrix inequality (LMI) based approach and robust Lyapunov feedback controller are associated.
