Dead-Time Distortion Shaping

Control of processes with dead time and input constraints using control signal shaping

Using the idea of ‘shaping the control signal’, the authors generalise the time-delayfilter-based deadbeat control for processes with dead time to a two-level control so that actuator saturation is avoided. The controller mimics experienced manual operation to provide a two-level control signal. At the first stage (level), the controller outputs a value very close to the actuator saturation bou...

Distortion of photon-correlation functions in detection systems with paralyzable dead-time effects

We introduce an analytical model of the influence of paralyzable dead time on registered photon-correlation functions. Distortions of correlation functions in the case of the Poisson point process, the doubly stochastic Poisson point process, and the pairwise point process are calculated. The model permits the analysis of detection systems with constant and random dead times. The results of the...

Investigation of purge time in cathodic dead-end mode PEMFC

 Recently, special type of fuel cells has been developed that operates in a Dead End mode. Working in this condition, the Dead-End fuel cell is supplied withhydrogen almost at the same rate of consumption. It is noteworthy to mention thatall of the water transport mechanisms have been considered in this simulation.Water accumulation that is directly proportional to the cell current is of a grea...

Dead-time compensators: A survey

This paper presents a review of the main dead-time compensators (DTC) described in literature. The paper analyses the basic Smith predictor (SP) showing its advantages and drawbacks. DTC structures designed to improve closed-loop characteristics and to control unstable systems are described. The paper concludes with some recommendations for designing dead-time compensator controllers. r 2007 El...
