3D I-SLSJF: A consistent sparse local submap joining algorithm for building large-scale 3D Map

Hu Gibson; Dissanayake Gamini; Huang Shoudong (IEEE, 2009)

This paper presents an efficient and reliable algorithm for autonomous robots to build large-scale three dimensional maps by combining small local submaps. The algorithm is a generalization of our recent work on two ...
Analysis of axial voltages and inter-bar currents in cast copper cage rotors during DC current injection as an aid to identify casting faults

Dorrell David; Frosini Lucia; Bottani Marcello; Galbiati Giacomo; Hsieh Min-Fu (IEEE, 2009)

In this paper an investigation is carried out to see if it is possible to assess the condition of a rotor by clamping it in a DC-current-injection rig and measuring voltages in bars at regular intervals down the axial ...
Body-Area-Network transmission power control using variable adaptive feedback periodicity

Moulton Bruce; Hanlen Leif; Chen June; Croucher Graham; Mahendran Lukshi; Varis Andrew (IEEE, 2010)

We propose a class of adaptive power control protocol, where the period between each feedback transmission is adaptively varied to accommodate run-time variation in the quality of each channel. Initial analyses suggest ...
Cogging Torque Reduction in Axial Flux Machines for Small Wind Turbines

Hsieh Min-Fu; Dorrell David; Yeh Y.; Ekram Samsul (IEEE, 2009)

This paper presents a technique for cogging torque reduction in an axial-flux permanent-magnet (PM) generator suitable for use in a small wind turbine. These machines can be compact and have high power density; they are ...
Design and Experimental Investigation of Demand Dependent Active Suspension for Vehicle Rollover Control

Wang Lifu; Zhang Nong; Du Haiping (IEEE, 2009)

This paper presents a novel design for Demand Dependent Active Suspension (DDAS) focusing on vehicle rollover control. Active suspensions take credit for improving ride comfort and handling performance, but to use active ...
Drive system analysis of a novel plug-in hybrid vehicle

Xu Wei; Zhu Jianguo; Guo Youguang; Dorrell David; Li Yongjian; Wang Yi (IEEE, 2009)

With breakthroughs in battery technology, plug-in hybrid electric vehicles (PHEVs), jointly powered by an electric drive and an internal combustion engine are becoming a realistic alternative. In a PHEV, the battery is ...
An Efficient Bayesian Framework For On-Line Action Recognition

Vezzani R; Cucchiara Rita; Piccardi Massimo (IEEE, 2009)

On-line action recognition from a continuous stream of actions is still an open problem with fewer solutions proposed compared to time-segmented action recognition. The most challenging task is to classify the current ...
An improved series equivalent circuit of a single-sided linear induction motor

Xu Wei; Zhu Jianguo; Dorrell David; Li Yaohua; Li Yongjian (IEEE, 2009)

The derivation of the equivalent circuit for a single-sided linear induction motor (SLIM) is not straightforward. Especially if it includes longitudinal end effects from the cut-open primary magnetic path, transverse edge ...
Robust Controller Design for Vehicle Semi-Active Suspensions with Electrorheological Dampers

Du Haiping; Zhang Nong (IEEE, 2009)

This paper presents a robust control approach for semi-active suspensions with electrorheological (ER) dampers considering system parameter uncertainties and control input constraint. By representing the suspension with ...
Speed sensorless direct torque control of 3-level inverter-fed induction motor drive based on optimized switching table

Zhang Yongchang; Zhao Zhengming; Zhu Jianguo; Xu Wei; Dorrell David (IEEE, 2009)

Three-level neutral-point-clamped (NPC) inverters are very appropriate for high-power adjustable-speed drive applications. Direct torque control is characterized by the merits of fast response, simple structure and strong ...
Starting torque analysis in skewed-cage induction motor with broken bar using a combined hybrid analytical/finite element technique

Dorrell David; Frosini Lucia; Bottani Marcello; Galbiati Giacomo (IEEE, 2009)

The aim of this paper is to analyze the positional variation of starting torque in a 3-phase induction motor. This can depend on different factors: manufacture of the rotor (fabricated or cast), skewing of the rotor bars, ...
