Open-loop and Closed-loop Optimization of Linear Control Systems

A canonical optimal control problem for linear systems with timevarying coefficients is considered in the class of discrete controls. On the basis of linear programming methods, two primal and two dual methods of constructing optimal open-loop controls are proposed. A method of synthesis of optimal feedback control is described. Results are illustrated by a fourth-order problem; estimates of ef...

Clinical requirements for closed-loop control systems.

Closed-loop (CL) therapy systems should be safe, efficacious, and easily manageable for type 1 diabetes mellitus patient use. For the first two clinical requirements, noninferiority and superiority criteria must be determined based on current conventional and intensive therapy outcomes. Current frequencies of hypoglycemia and diabetic ketoacidosis are reviewed and safety expectations for CL the...

Analysis of Reset Control Systems Consisting of a FORE and Second - Order Loop

Reset controllers consist of two parts a linear compensator and a reset element. The linear compensator is designed, in the usual ways, to meet all closed-loop performance speci cations while relaxing the overshoot constraint. Then, the reset element is chosen to meet this remaining step-response speci cation. In this paper, we consider the case when such linear compensation results in a second...

Closed Loop Control

Background The purpose of this study was to evaluate electrode temperatures obtained using a radiofrequency ablation system that incorporates closed loop feedback control to achieve preset target electrode temperatures and to determine if closed loop temperature control results in a lower incidence of developing a coagulum. Methods and Results Two hundred seventy patients underwent catheter abl...
