Feedback control in anaesthesia
International journal of clinical monitoring and computing, 1997This review considers the some of the methods of automatic control which are usable in medicine. The features of each type of control system are explained and the advantages and disadvantages summarised. The author has attempted to maintain a balance between what is possible with the excellence of modern engineering, and what is feasible in the ...

Feedback control for clinicians
Journal of Clinical Monitoring and Computing, 2013Although feedback control and automation has revolutionized many fields of human activity, it has yet to have a significant impact on healthcare, particularly when a patient is in the loop. Although there have been a number of studies concerned with closed-loop control of anesthesia, they have yet to have an impact on clinical practice.

On Receding Horizon Feedback Control
IFAC Proceedings Volumes, 1981Abstract Receding horizon feedback control (RHFC) was originally introduced as an easy method for designing stable state-feedback controllers for linear systems. Here we generalize those results so they will apply to the control of nonlinear autonomous systems, and we develop a performance index which is minimized by the RHFC (inverse optimal control

FEEDBACK CONTROL OF THE CHEMOTHERAPY OF HIV
International Journal of Bifurcation and Chaos, 2000Using a model which describes the interaction of the immune system with the human immunodeficiency virus (HIV), we introduce a feedback control strategy of chemotherapy in an early treatment setting, where the control represents the percentage of effect chemotherapy has on the viral production.

Controllability Subspaces and Feedback Simulation
SIAM Journal on Control and Optimization, 1975The concepts of input chain and controllability chain are introduced, and the structure of controllability subspaces of a linear system is investigated. It is shown that the input and controllability chains are the fundamental feedback invariants of a linear system.The feedback simulation problem (a generalization of the feedback equivalence problem ...

Our body uses feedback loops to regulate such things as temperature, oxygen concentration in the blood, cardiac output, and the blood concentration of glucose. We analyze the general properties of a negative feedback loop and introduce concepts such as the operating point and the open-loop gain (OLG).

International Journal of Systems Science, 1992
Abstract The two main results are the necessary and sufficient conditions for the existence of a causal and a strongly causal feedback controller which realizes a given behaviour on a given system. The proofs are constructive. If the given system is a discrete event system or an ordinary discrete event system, then a controller could also be a discrete
