Evidence of a mechanism of neural adaptation in the closed loop control of directions
International Journal of Intelligent Computing and Cybernetics, 2010PurposeUsing cortical neurons of animals to control external devices allows experimenters a unique opportunity to study the capability of the brain to utilize a new actuator. The purpose of this paper is to investigate the ability of unrestrained rats to control a directional task using motor cortical signals.Design/methodology/approachIn freely moving

Closed-loop control mechanical ventilation
1999Closed-loop control mechanical ventilation includes any ventilation mode that is specifically designed to maintain the constancy of a given physiological respiratory parameter, continuously monitored (the controlled variable), by means of automatic adjustments of one or more ventilator settings (the control variables).

A Closed-Loop Mechanical Ventilation Controller With Explicit Objective Functions
IEEE Transactions on Biomedical Engineering, 2004A closed-loop lung ventilation controller was designed, aiming to: 1) track a desired end-tidal CO2 pressure (Pet CO2), 2) find the positive end-expiratory pressure (PEEP) of minimum estimated respiratory system elastance (Ers,e), and 3) follow objective functions conjectured to reduce lung injury.

Closed-Loop Control of the Inspired Fraction of Oxygen in Mechanical Ventilation
Journal of Clinical Monitoring and Computing, 2002Supplemental oxygen treatment of patients on mechanical ventilation is crucial in maintaining the patients' oxygen levels in the normal range. The purpose of this study was to evaluate the effectiveness of a closed-loop controller for automatic adjustment of the fraction of inspired oxygen, FIO2.

Closed-loop Control in Mechanical Ventilation
1993In the 1960s and the 1970s, control and assist volume controlled modes were the state-of-the-art for mechanical Ventilation. The aim was to maintain normal gas exchange and blood gas values. By the end of the 1970s, most clinieians realized the importance to allow the patients to breath spontaneously between the controlled respiratory cycles ...

Variational integrators for open‐loop and closed‐loop optimal control of mechanical systems
PAMM, 2017AbstractMechanical systems have structural properties, e.g. symplecticity, symmetry, and a specific energy behavior, which get lost in standard integration methods. Therefore, symplectic integration methods are used in simulation and control of mechanical systems.

Dynamic Mechanism Design for Human-in-the-Loop Control of Building Energy Consumption
2019 American Control Conference (ACC), 2019Integrating the preferences of building occupants for efficient building energy management has the potential for significant energy savings. In this paper, we present a new dynamic mechanism that achieves ex-post incentive compatibility, i.e., the occupants reveal their privately-held preferences truthfully in every time period.

Mechanical Pumped Cooling Loop for Spacecraft Thermal Control
SAE Technical Paper Series, 1996<div class="htmlview paragraph">The Mars Pathfinder (MPF) Spacecraft, scheduled for a December 1996 launch to Mars, uses a mechanically pumped loop to transfer dissipated heat from the insulated lander electronics to an external radiator. This paper discusses the tradeoffs performed before choosing a mechanical pumped loop as the thermal control ...

A dual-loop robust controller for DC electro-mechanical servo system
International Journal of Modeling, Simulation, and Scientific Computing, 2015In order to further improve the tracking performances of the conventional disturbance observer (DOB)-based control schemes, a dual-loop robust control scheme is proposed for DC electro-mechanical servo system. The outer-loop sliding mode controller (SMC) is designed in order to deal with the impacts from the remainder equivalent disturbances, which is
