Closed-loop Control of Decision System and Equipment Effectiveness

Closed-Loop Measurement of Equipment Efficiency and Equipment Capacity

Formal definitions for the components of efficiency and capacity, mathematical formulas for computing overall efficiency, and data collection strategies are proposed for rigorous measurement of equipment efficiency and equipment capacity. Measurement of overall equipment effectiveness (OEE) under the TPM paradigm is revised to become a true quantitative measure of efficiency that we term overal...

Motor / Tachometer Closed - Loop Speed Control System

Clinical decision support systems: the fascination with closed-loop control.

To the engineer a closed-loop control system refers to using a controller with a feedback loop to control states or outputs of a dynamic system. That dynamic system might be the cruise (speed) control on your automobile, maintaining a patient’s paO 2 with a ventilator, controlling depth of anesthesia with an anesthesia machine, or controlling arterial blood pressure with medications from an IV ...

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...

Closed Loop Control Methods

In this paper, a systematic overview of PLL-based closed-loop control methods for interleaved DCM/CCM boundary boost PFC converters is presented. It is shown that the PLL-based closed-loop methods always provide stable operation, unlike the open-loop control methods, where the only method which results in stable operation is the slave synchronization to the turn-on instant of the master with cu...
