DEVELOPMENT OF NOVEL INSTRUMENTATION INCORPRATING MAGNETORESISTIVE ENCODERS FOR THE MEASUREMENT OF ANGULAR
SALEH, SHARIEF (2018 , Master Thesis)As rotation dependent technologies emerge, the need of having a feedback about their rotational behavior became a necessity in order to control them. Many types of sensors, based on various operation principles are available ... -
A high precision resolver-to-DC converter
Benammar, Mohieddine; Ben-Brahim, Lazhar; Alhamadi, Mohd A. ( IEEE , 2005 , Article)A newly developed resolver converter, providing a pseudolinear voltage proportional to the shaft angle, is presented. This converter is based on a new concept involving the absolute values of the demodulated sine and cosine ... -
A new angle determination method for resolvers
Ben-Brahim, Lazhar; Benammar, Mohieddine; Alhamadi, Mohd; Al-Emadi, Nasser; Al-Hitmi, Mohammed ( IEEE , 2008 , Conference Paper)A new low cost method for converting the amplitudes of the sine/cosine signals generated by the resolver into a measure of the angle of its shaft. The new method operates without lookup tables (LUT), and takes advantage ... -
A new iterative learning control method for PWM inverter current regulation
Ben-Brahim, Lazhar; Benammar, Mohieddine; Alhamadi, Mohd A. ( 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 ... -
A novel converter for sinusoidal encoders
Benammar, Mohieddine; Ben-brahim, Lazhar; Alhamadi, Mohd A.; El-Naimi, Mohamed ( IEEE , 2006 , Conference Paper)The paper presents a novel and low cost method for determining the angle from sine and cosine signals generated by angular position sensors such as resolvers and sinusoidal encoders. The proposed scheme is based upon the ... -
A novel method for estimating the angle from analog co-sinusoidal quadrature signals
Benammar, Mohieddine; Ben-brahim, Lazhar; Alhamadi, Mohd A.; Al-Naemi, Mohamed ( Elsevier , 2008 , Article)The paper presents a new low cost and accurate method for determining the angle from sine and cosine signals produced by resolvers and sinusoidal encoders. In the proposed scheme, multiple phase-shifted sinusoids (PSS) are ... -
A Novel Resolver-to-360° Linearized Converter
Benammar, Mohieddine; Ben-Brahim, Lazhar; Alhamadi, Mohd A. ( IEEE , 2004 , Article)A novel and simple resolver-to-dc converter is presented. It is shown that by appropriate processing of the sine and cosine resolver signals, the proposed converter may produce an output voltage proportional to the shaft ...
