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 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 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 ... -
Precise method for linearizing sine and cosine signals in resolvers and quadrature encoders applications
Alhamadi, Mohd A.; Benammar, M.; Ben-brahim, L. ( 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, ...
