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 ...

42nd IEEE International Conference on Decision and Control (IEEE Cat. No.03CH37475), 2004
In this work a new method for designing predictive controllers for linear SISO systems is presented. It uses only one prediction of the process output J time intervals ahead to compute the correspondent future error. The predictive feedback controller is defined by introducing a filter that weights the last w-predicted errors.

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.

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, 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 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.

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 ...

Adaptive reservations for feedback control
49th IEEE Conference on Decision and Control (CDC), 2010In this paper, we start from an assigned control law with known probability distributions of its execution time. Our goal is to identify an optimised scheduling policy that allows us to strike an acceptable tradeoff between control performance and consumption of computation resource.

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

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.
