An open-loop technique for angle determination from position encoders
(
IEEE
, 2008 , Conference Paper)
The paper presents a novel technique for the determination of the angle from low-frequency quadrature cosinusoidal signals produced, for example, by position sensors. In the presented scheme applied to a resolver, the ...
Voltage stability evaluation of real power transmission system using singular value decomposition technique
(
IEEE
, 2008 , Conference Paper)
Voltage stability is an important factor that needs to be taken into consideration during the planning and operation of power systems in order to avoid voltage collapse and subsequently partial or full system blackout. ...
Fuzzy system applications for identification of weak buses in power systems
(
King Fahd University of Petroleum and Minerals
, 2002 , Article)
In this paper a simple new algorit hm for identifying the weak buses in a power system for voltage stability study is presented. The proposed algorithm is based on fuzzy set theory. Two membership functions, one for voltage ...
Iterative learning control for variable frequency drives
(
IEEE
, 2008 , Conference Paper)
Variable Frequency Drives (VFD) are subject to various types of disturbances especially cyclical ones. These periodic disturbances are difficult to compensate by conventional controllers. Repetitive control can only ...
Generalized dynamic spectrum access: An order statistics design perspective
(
Elsevier GmbH
, 2008 , Article)
A new adaptive multiple access scheme based on the theory of order statistics is introduced. The proposed algorithm employs a semi-random allocation mechanism that limits subchannel selection to the highest-gain subchannels. ...
Digitally-tuned resolver converter
(
Elsevier B.V.
, 2009 , Article)
Sinusoidal encoders provide electrical signals related to the sine and cosine of the mechanical shaft angle θ. An analog converter is described for the linearization of these signals and hence for linear computation of θ. ...
