Multi-Speed Ratio Variable System to Transmit Power and Motion Continuously

Multi-objective Optimization of Hybrid Electric Vehicle Equipped with Power-split Continuously Variable Transmission

This paper aims to find the efficient state of hybrid electric vehicle (HEV) by simultaneous optimization of the control strategy and the power train. The power transmission employed in this vehicle is a power-split continuously variable transmission (CVT) which uses several fixed ratio mechanisms. After describing this transmission, the rules of electric assist control strategy are introduced....

Transmit Power Efficiency of a Multi-Hop Virtual Cellular System

Recently, there is a strong demand for higher speed data transmissions in cellular mobile communications systems. However, there will be a serious problem; as data transmission rate becomes higher, the peak transmit power becomes larger. To decrease the peak transmit power while increasing the data transmission rate, the cell size should be made significantly small. We proposed a virtual cellul...

Control of a Continuously Variable Transmission System

This paper proposed control strategies for the modern mechatronic Continuously Variable Transmission (CVT) System using three different techniques; The Ziegler-Nichols, Linear Quadratic and Pole-Placement methods. The results of the system responses of the designed control schemes were successfully simulated using MATLAB. Comparing the results showed that controller implemented using the Pole-P...

Modeling and Simulation of Variable Speed Variable Frequency Electrical Power System in More Electric Aircraft

Abstract: The More Electric Aircraft (MEA), Variable Speed Variable Frequency (VSVF) and Electrical Power System (EPS) has lager generating capacity and higher energy efficiency than the conventional Constant Speed Constant Frequency EPS, but the generators of MEA have to working as redundant power supplies to improve the power supply reliability, instead of parallel power supply. To study the ...
