This study presents an intelligent hybrid energy management system for electric scooters. The proposed power distribution approach is controlled by a bi-directional converter. The management system is designed according to the property of the battery, supercapacitor, and motion control requirements. The proposed approach keeps the battery working in an effective zone and hence extends the lifespan...
The purpose of signal restoration is to acquire a clean signal from the degraded signal which contains blur and noise. In this paper, a modified Tikhonov regularization method based on the standard Tikhonov regularization matrix is proposed, and the corresponding preconditioner is designed to accelerate the convergence of the proposed algorithm. The proposed method shows the best performance than...
With the rapid development of Location Based Service (LBS) applications and the continual improvement of intelligent terminal technology, study on smartphone-based indoor positioning approach has turned to be the hot topic quickly in recent years. In this paper, a WiFi-assisted Pedestrian Dead Reckoning (PDR) algorithm based on activity recognition is proposed on the smartphone platform to realize...
The characteristics of sol-gel glass phosphor have been investigated. The sol-gel glass phosphor showed 1.5% and 9.5% more efficient in quantum efficiency and luminous efficiency respectively than sintered glass phosphor.
This paper presents the application of an Improved Particle Swarm Optimization (IPSO) technique for adjusting the gains of a PID controller. Two system plants with heavily oscillatory and moderate oscillatory associated with time delay are simulated numerically. A cycloid signal for mimicking the real industrial motion profile is applied. PID control parameters tuned by IPSO and MATLAB toolbox are...
In order to utilize braking energy of metro vehicles at high recovery efficiency, it is necessary to research the metro supply network and metro vehicles. The simplified models of the metro supply network and vehicles are presented based on Simulink/SimPowerSystem via external characteristics. And the detail of some important modules are described in this paper. Meanwhile the character of the metro...
