A novel converter for sinusoidal encoders
(
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 new angle determination method for resolvers
(
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
(
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 ...
Digital control for UPS inverters
(
IEEE
, 2003 , Conference Paper)
PWM inverters digital controls with dead-beat re sponse, for UPS applications, are reviewed. To improve the output waveforms of the PWM inverter, several modern control techniques are applied together with the deadbeat ...
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 closed-loop converter for sinusoidal encoders - Preliminary results
(
IEEE
, 2009 , Conference Paper)
Sinusoidal position transducers provide accurate and reliable representation of the mechanical position of their shafts. The sine/cosine transducers signals may be used in open loop or closed loop arrangements for the ...
