This paper surveys a brief history of agriculture, demonstrating how advances in genetics, equipment, and management practices have resulted in the remarkable productivity experienced by today's agriculture industrial complex. We then show that progress in each of these areas is, in part, the result of new solutions to a feedback-control problem ...

Feedback control of anaesthesia
Current Opinion in Anaesthesiology, 1998Feedback control of anaesthesia can improve the quality of patient care while reducing the administration and cost of anaesthetic drugs. Systems have been available for several years to control blood pressure and neuromuscular blockade. Control of anaesthetic depth has been reported using the median frequency of the electroencephalogram.

Dynamics of Nonlinear Feedback Control
Neural Computation, 2007Feedback control in neural systems is ubiquitous. Here we study the mathematics of nonlinear feedback control. We compare models in which the input is multiplied by a dynamic gain (multiplicative control) with models in which the input is divided by a dynamic attenuation (divisive control). The gain signal (resp.

On interconnections, control, and feedback
IEEE Transactions on Automatic Control, 1997The control problem is formulated in terms of interconnections. The interconnections of linear time-invariant systems are studied from this point of view. Two main results are obtained. Any polynomial can be obtained as the characteristic polynomial of an interconnection with a given plant, provided the plant is not autonomous.

Feedback control with Posicast
IEEE Transactions on Industrial Electronics, 2003An alternative way to use Posicast to damp oscillations in lightly damped control systems is proposed in this paper. Specifically, it is suggested that the Posicast technique be used within a feedback system, instead of the classical feedforward configuration.

ISA Transactions, 2007
In this work a control structure capable of handling controllability problems, which emerge from the presence of constraints, and improve the performance of the system by coordinating the use of several manipulated variables is introduced. In this scheme, the primary manipulated variable is used to handle the transient response while the auxiliary ...

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.

Symbolic feedback control for navigation
IEEE Transactions on Automatic Control, 2006We discuss the generation of symbolic feedback control sequences for navigating a sparsely-described and uncertain environment, together with the problem of sensing landmarks sufficiently well to make feedback meaningful. We explore the use of a symbolic control approach for mitigating the lack of a detailed map of the environment and for reducing the ...

ISA Transactions, 2003
In this work a new method for designing predictive controllers for linear single-input/single-output systems is presented. It uses only one prediction of the process output J time intervals ahead to compute the correspondent future error. Then, the predictive feedback controller is defined by introducing a filter which weights the last w predicted ...

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 ...
