Given a right coprime MFD of a strictly proper plant P (s) = NR (s)DR (s) −1 with DR (s) column proper a simple numerical algorithm is derived for the computation of of all polynomial solutions [XL (s) , YL (s)] of the polynomial matrix Diophantine equation XL (s)DR (s) + YL (s)NR (s) = DC (s) which give rise to the class Φ (P, DC) of proper compensators C (s) := XL (s) −1 YL (s) that when empl...

This paper proposes a new method for text-dependent speaker recognition. The scheme is based on learning (what we refer to as) speaker-specific compensators for each speaker in the system. The compensator is essentially a speaker to speaker transformation which enables the recognition of the speech of one speaker through a speaker-dependent speech recognition system built for the other. Such a ...

In this paper, a method for auto-tuning of a fractional order leadlag compensator using relay feedback tests is proposed. A design method for this kind of compensators is discussed, based on the magnitude and phase measurement of the plant to be controlled from relay feedback tests at a frequency of interest. Simple relationships among the parameters of this fractional controller are establishe...

High quality sound reproduction by loudspeakers is increasingly problematic if the dimensions of the loudspeaker decrease. To produce enough power, large diaphragm excursions are needed which give rise to significant distortions especially at very low frequencies. Instead of improving the mechanical construction of the transducer we apply a feedforward nonlinear digital inverse circuit. Results...

This paper introduces the idea of using mechanical steering compensators to improve the dynamic behavior of high-performance motorcycles. These compensators are seen as possible replacements for a conventional steering damper and comprise networks of springs, dampers, and a less familiar component called the inerter. The inerter was recently introduced to allow the synthesis of arbitrary passiv...

Derives a new rank condition which guarantees the arbitrary pole assignability of a given system by dynamic compensators of degree at most q. By using this rank condition the authors establish several new sufficiency conditions which ensure the arbitrary pole assignability of a generic system. The authors' proofs also come with a concrete numerical procedure to construct a particular compensato...

Based on a new definition of non-active current/power, this paper presents the application of a parallel active filter for the compensation of non-periodic currents. Analysis of the compensation characteristics required for a variety of non-periodic currents such as those associated with arc furnaces is presented. In addition, the corresponding current rating and energy storage requirements of ...
