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 ...
Novel linearizer for tangent/cotangent converter
(
IEEE
, 2009 , Conference Paper)
Resolvers and other types of sinusoidal encoders provide electrical signals whose amplitudes are related to the sine and cosine of the mechanical shaft angle ¿ over the full 360° range. The tangent/cotangent converter, ...
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 ...
Development of a remote lab for electrical engineering program
(
IEEE Computer Society
, 2009 , Conference Paper)
A remote lab for electrical engineering experiments has been designed and implemented. This has been intended as a platform that supports existing traditional labs by offering lab experiments that serve some of the student ...
Optimal power allocation for relayed transmissions over Rayleigh-fading channels
(
IEEE
, 2004 , Article)
Relayed transmission is a way to attain broader coverage by splitting the communication link from the source to the destination into several shorter links/hops. One of the main advantages of this communication technique ...
Precise method for linearizing sine and cosine signals in resolvers and quadrature encoders applications
(
IEEE
, 2004 , Conference Paper)
Resolvers and quadrature encoders provide electrical signal related to the sine and cosine of the mechanical shaft angle over the full 360 degree range. A converter is described for the linearization of these signals, ...
A neutral point voltage balancing method for multi-level GTO inverters
(
IEEE
, 2006 , Conference Paper)
The balancing problem of the DC-link capacitor voltage is inherent in the NPC inverter. It is extremely important to keep the upper and lower DC-link capacitor voltages balanced to guarantee the three level operation of ...
A new iterative learning control method for PWM inverter current regulation
(
IEEE
, 2003 , Conference Paper)
AC servomotor speed or current controller based on PI control and/or optimal control, can not eliminate the cyclical fluctuations of speed or current when subject to periodic disturbances. PWM inverters output waveforms ...
