Multimodal telepresence and teleaction systems enable a human operator to perform in remote environments through a telerobot and a communication network. In addition to audio-visual information communication, from a control point of view, the stability of the networked force feedback control system is the key challenge. This paper discusses a human adapted deadband control approach for network ...

Adjusting a drifting process to minimize the expected sum of quadratic off-target and fixed adjustment costs is considered under unknown process parameters. A Bayesian approach based on sequential Monte Carlo methods is presented. The benefits of the resulting ‘‘deadband’’ adjustment policy are studied. r 2007 Elsevier B.V. All rights reserved.

This paper discusses the optimal design of Variable Structure Controller (VSC) applied to the Load Frequency Control (LFC) problem. The controller was designed by an optimal method that utilizes Tabu Search (TS) algorithm. The proposed method has been applied to a single nonreheat area model that includes nonlinearities in the form of Generation Rate Constraint (GRC) and governor deadband backl...

Maintaining the stability of active power and frequency between generator network system is very important, because if output are unstable, it will cause damage to generator. influenced by speed drop deadband settings. Speed ​​droop a percentage number that states sensitivity generating unit in responding changes, while change value at which governor begins respond increase or decrease generato...

Complex multimedia systems like telepresence and teleaction systems are rapidly gaining relevance in both modern science and technology. The challenging integration of various multimodal data streams is a main topic in current research activities. While the processing and coding of video and audio data as the two most important modalities for the human being has been excessively thematized in t...

One of the key challenges in current bilateral teleoperation systems is the high data packet rate necessary for the transmission of the sampled command and sensor data. We present a novel, psychophysically motivated approach to reduce the packet rate based on a deadband transmission strategy. Data packets are only sent if the sampled signal changes more than a given threshold value. The thresho...

A class A/B BiCMOS power op-amp designed to drive the L/R load of a disk drive head actuator is presented. The amplifier uses totem pole NMOS outputs instead of bipolar devices to avoid the high collector resistance in the simplified process used. A unique floating buffer technique regulates the quiescent totem pole current of the output devices and provides control for deep triode NMOS operati...

Consider a machine that can start production off-target where the initial offset is unknown and unobservable. The goal is to determine the optimal series of machine adjustments that minimize the expected value of the sum of quadratic off-target costs and fixed adjustment costs. Apart of the unknown initial offset, the process is supposed to be in a state of statistical control, so the process m...
