IEE Colloquium on 'Achieving an Acceptable Confidence Level in EMC Measurements' (Digest No.117)
Risk assessment for BCI testing
A system-level test method has been devised that uses all measured transfer function information, thus giving statistical information on the possibility of over or under testing a component. This statistical information, comprising mean and...
The effects of variations in wave impedance in the coupling of large lossy bodies to external electromagnetic fields
Describes a theoretical analysis of the illumination of a hollow, conductive object containing a wire by a non-planar wave. Much EMC testing is performed at antenna-test object separation distances that are small compared to the wavelength....
Reproducibility and relevance in current injection testing
Immunity testing by current injection onto system cables is an economically attractive alternative to radiated field testing, but correlation between the two has proved difficult. The basic characteristics of the two methods are reviewed as...
The effects of wave polarisation on the performance of radiated emission measurement test sites
Presents a simplified analysis of the coupling between an EUT (equipment under test) and the antenna for any radiated emission test site. The analysis illustrates the problems with inter-site comparison.<<ETX xmlns:mml="http://www.w3.org/19...
Reducing the uncertainty in EMC measurements due to chamber characteristics and system mismatch
Examines the sources of uncertainty in EMC measurements carried out in the EMC Test House Facility at British Aerospace (Dynamics) Limited, Filton. The dominant sources of error are identified and ways of reducing these in order to minimise...
Radiated emission measurements in screened rooms; techniques for the reduction of calibration uncertainty
Describes the measurement tools, and also a preliminary calibration technique which, in favourable circumstances, enables screened room measurements in the 1-30 MHz frequency range to be used to predict free-space radiation from the simulat...
Pade extended prony (PEP) model reduction for linear multivariable systems
In this paper we develop a general idea of Pade.ex tended Prony (PEP) modelling which reduces to the classical Pade and.(extended) Prony models as special cases. The formulation includes development of PEP models based on min /spl par/ /spl...
Contraction and related mappings: theory and applications
This paper discusses the theoretical aspects of contraction and related mappings and their application to certain systems engineering problems. It is demonstrated how the fixed point property of contraction mappings can be exploited to esta...
Evaluation of Factors Affecting the Performance of Controller Designed for Robot Manipulators using the Theory of Variable Structure Systems
For the evaluation of factors which affect the performance of controllers designed for robot manipulators using the theory of Variable Structure Systems (VSS), control torques, reaching time, chattering and control parameters are suggested ...
