This paper considers measurement-based admissions control procedures for Controlled-Load services [Wro96]. First, we discuss some of the factors that reduce the requirements on a measurement-based admissions control procedure in an Internet environment with a strong mix of realtime and data traffic. Next, we discuss measurement-based admissions control procedures for Controlled-Load services th...

Abstract. A new multi-loop controlled low dropout (LDO) regulator featuring with improved transient response and low quiescent current is presented in this paper. The proposed Multi-Loop Control (MLC) technique adopting both feed-back and feed-forward control methods to realizes the fast response ability by regulating the load current and output voltage through separate loops rapidly. In additi...

This paper presents an approach to improve dynamic responses of digitally controlled dc–dc converters using nonuniform analog-to-digital (A/D) quantization of the output voltage error. The nonuniform A/D quantizer parameters are selected to achieve improved step-load transient responses without compromising stability margins. The implementation, which includes a programmable A/D quantizer and a...

In this paper, a new simulink model for a single phase induction motor is proposed using double field revolving theory. To maintain a constant fluid flow with a variation in the pressure head, drives like Fan load and Pump load are operated with closed loop speed control. For non linear loads, closed loop speed control is achieved using a neural network controller. A comparative study has been ...

Class E synchronous rectifier regulating the output voltage at a fixed switching frequency is presented, analyzed and experimentally verified. This rectifier is derived from a class E low dv/dt rectifier by replacing a rectifier diode with a controlled switch. The rectifier is driven by a sinusoidal current source, and the output voltage is regulated by vary the conduction time of the controlle...

The relation between task properties, system performance and operator mental load in supervisory control is investigated using an artificial model of a pasteurisation plant. The relation is evaluated using the degree of automation which is based on the relative weights of the manually controlled tasks. Three ways of calculating task weights are investigated, based on 1) the mental load perceive...

We hypothesized that recently formed, incompletely mineralized, and thus, relatively deformable osteons in the equine third metacarpus enhance in vitro load-controlled fatigue life in two ways. Macroscopically, there is a compliance effect, because reduced tissue elastic modulus diminishes the stress required to reach a given strain. Microscopically, there is a cement line effect, in which new ...

Phase-shifted converters are practically important to provide high conversion efficiencies through soft-switching techniques. However, the limitation on a resonant inductor current in the converters often leads to a non-fulfillment of the requirement of minimum load current. This paper presents a new power electronics control technique to enable the dual features of bi-directional power flow an...

Real-time control strategies and their performance related to the optimal control trajectories for a diesel-electric powertrain in transient operation are studied. The considered transients are steps from idle to target power. A non-linear four state-three input mean value engine model, incorporating the important turbocharger dynamics, is used for this study. The strategies are implemented usi...
