A novel amplitude-to-phase converter for sine/cosine position transducers
(
Taylor and Francis Group
, 2007 , Article)
Resolvers and various other types of sine/cosine encoders are used for both angular and linear position sensing. These devices provide analogue signals in the form of the sine and the cosine of an angle related to the ...
Precise, wide-range approximations to arc sine function suitable for analog implementation in sensors and instrumentation applications
(
IEEE
, 2005 , Article)
This paper presents four newly developed algebraic approximations of the inverse sine function, defined for the full [-1,+1] input range. These approximations contain few terms, and have numerical coefficients with low ...
Design and Assembly of Miniature Zirconia Oxygen Sensors
(
IEEE
, 2004 , Article)
Zirconia oxygen sensors are highly selective solid-state devices used for many applications, including combustion control for better fuel economy and lower emissions. Stabilized zirconia electrolyte meets the device ...
Theory and simulation of a miniature zirconia sensor for control of the air-to-fuel ratio in combustion systems
(
IEEE
, 2001 , Article)
The theory of operation on both sides of stoichiometry of a miniature zirconia oxygen pump-gauge incorporating a diffusion hole is discussed. Computer simulation of the sensor output when used for monitoring the air-to-fuel ...
Harmonic modeling of linear and nonlinear loads based on Kalman filtering algorithm
(
Elsevier
, 2004 , Article)
Most harmonic nonlinear load modeling techniques developed in the last two decades, assume that the load connected to the load bus has a constant admittance, inductive or capacitive, which depends on the mode of operation ...
Fuzzy linear parameter estimation algorithms: A new formulation
(
Elsevier
, 2002 , Article)
In this paper, we present a new formulation of a fuzzy linear estimation problem as one of the linear programming where the objective is to minimize the spread of the data points, subject to constraints on each measurement ...
Frequency and harmonics evaluation in power networks using fuzzy regression technique
(
Elsevier
, 2003 , Article)
A new technique for frequency and harmonic evaluation in power networks is proposed in this paper. This technique is based on fuzzy linear regression and uses the digitized voltage samples, which are fuzzy numbers, to ...
A new digital transformation for harmonics and DC offset removal for the distance fault locator algorithm
(
Elsevier
, 2004 , Article)
This paper presents a new application of Park's transformations to identifying the positive sequence of the fundamental components of the three-phase voltage or current signals needed for fault locator algorithm. The problem ...
Identification of individual types of harmonic loads in an electric power system-bus
(
Elsevier
, 2004 , Article)
Some buses in a power system feed power to loads that are sources of harmonics. This type of bus is called a complex-bus. This paper provides a new application of the constrained least absolute value algorithm (LAV) to ...
Park's transformation application for power system harmonics identification and measurements
(
Taylor & Francis
, 2003 , Article)
This paper presents the application of Park's transformation for identifying and measuring power system harmonics. One of the advantages of the proposed technique is that it does not need a model for the harmonics components ...
