چکیده
The present contribution shows an analytical method of the calculus of the torque ripple and current waveforms of a universal motor supplied by a triac directly from the network. The triac output voltage waveform is formulated by the complex Fourier series. The armature reaction of the motor is included in the calculus. The motor performance is computed using the circuit parameters determined by measurements. The calculated current waveforms are compared with the measured ones.

Flux search controller technique is not only cost effective and easy to implement but al...
متن کاملA fast algorithm for multiresolution discrete Fourier transform
The paper presents a fast algorithm for the calculation of a multiresolution discrete Fourier transform. The presented approach is based on the realization of the Fast Fourier Transform for each frequency resolution level. This algorithm allows reducing the number of complex multiplications and additions compared to the method consisting in the multiplication between the input signal expressed ...
متن کاملPosition estimation for PMSM drive equipped with the motor choke
The paper presents results of studies on the sensorless drive with permanent magnet synchronous motor (PMSM) supplied through the motor choke. The position is estimated using a modified Luenberger observer. Its modification consists in using a PII correction function instead a proportional one, which gives smaller estimation errors. The advantages of that observer structure are simple structure...

متن کاملVoice Conversion Using A Two-Factor Gaussian Process Latent Variable Model
This paper presents a novel strategy for voice conversion by solving style and content separation task using a two-factor Gaussian Process Latent Variable Model (GP-LVM). A generative model for speech is developed by interaction of style and content, which represent the voice individual characteristics and semantic information respectively. The interaction is captured by a GP-LVM with two laten...
