Comparison of hybrid propulsion drive schemes
IEEE Electric Ship Technologies Symposium, 2005., 2005This paper provides a brief overview of a hybrid drives which have become popular in recent years. These drives combine two or more multilevel power inverters to obtain exceptional power quality which is necessary for Naval propulsion applications. Furthermore, for ship propulsion, where it may be difficult to obtain several isolated dc voltage sources,

Motor driving/braking control scheme with integration of multiple driving components
Asian Journal of Control, 2020AbstractThis paper develops a modular multilevel inverter which integrates driving/braking control schemes in a unit for electric vehicles. The multiple driving components are used to balance surge voltage/current across the last stage power MOSFETs due to abrupt back electromotive force (EMF) generated by the permanent magnet synchronous motor (PMSM).

Driving Scheme for AMOLED Based on FPGA
Chinese Journal of Liquid Crystals and Displays, 2011This paper presents a driving scheme based on FPGA for the 17.8 cm(7 in) active matrix organic light emitting display(AMOLED) using μc-Si TFT technology.This scheme is easy to be implemented.It doesn't require external cache,and consequently the difficulty of PCB layout and system control is reduced.It presents a method connecting screen with IC to ...

Driving waveforms of partial writing scheme for FLCD
Displays, 1993Abstract The authors have developed driving waveforms for a new partial writing scheme. In the new partial writing scheme, the selected pixel which will change its image is rewritten, but the selected pixel which will not change its image is not. However, the driving waveform applied to the selected pixel which will not change its image must give the

A Novel Drive-Thru Internet Channel Access Scheme
IEEE Communications Letters, 2014This letter proposes a novel and complexity minimal random vehicle selection (RVS) scheme for drive-thru Internet systems. A mathematical framework is established with the objective of modeling a vehicle's onboard unit's buffer and evaluating its performance under RVS in terms of several quality-of-service metrics.

A Driving Scheme for AMOLED Displays Based on Current Feedback
IEEE Custom Integrated Circuits Conference 2006, 2006A scheme of driving AMOLED displays with amorphous silicon (a-Si) thin film transistors (TFTs) is presented. By exploiting current feedback, a transresistance amplifier as column driver, and an accelerating current pulse, the driving scheme provides fast programming and low sensitivity of OLED current to shift in VT in a-Si TFTs.

A Speed Control Scheme of Eco-Driving at Road Intersections
2015 Third International Conference on Robot, Vision and Signal Processing (RVSP), 2015The human driving habits of slamming the accelerator or brake usually make unnecessary fuel consumption and carbon emissions. This paper proposes a speed control scheme of eco-driving at road intersections to avoid frequent stop-and-go driving. The scheme can smooth over the variation of vehicle speed, reduce the waiting time of the vehicle and improve

A Drive Scheme for the GaAs-Si Light-Activated Switch
IBM Journal of Research and Development, 1965The development of a GaAs-Si light-activated switch, designed to serve as a building block in an integrated electronic gating system (multiplexor), has been reported 1–3 It was found that the usefulness of the gating system could be greatly amplified if a simple drive scheme could be designed to operate compatibly with it.

Experimental Evaluation of Identification Schemes on a Direct Drive Robot
Robotica, 1997This paper describes the experimental evaluation of three identification schemes to determine the dynamic parameters of a two degrees of freedom direct-drive robot. These schemes involve a recursive estimator while the regression models are formulated in continuous time.

An innovative direct self-control scheme for induction motor drives
IEEE Transactions on Power Electronics, 1997The paper presents a new direct self-control (DSC) scheme for induction motor drives using the stator voltage third harmonic component in order to estimate the air-gap flux and the torque as well as to synchronize the supply voltage vector. Compared to previous DSC schemes the new one is independent from any motor parameter variation, specifically on ...
