during the last years, the concept of input congestion and technical ineff-ciency in data envelopment analysis (dea), have been investigated by manyresearchers. the motivation of this paper is to present models which obtain thedecreased output value due to input congestion and technical ineciency. more-over, we extend the models to estimate input congestion, technical ineciencyand output red...

This paper proposes an improved control method based on modified Delta-Sigma Modulator (DSM) to enhance transient response and improve harmonic contents of buck DC-DC converter. The main advantages of the proposed method are improving the output voltage frequency spectrum, correction of the output voltage harmonic contents and sideband harmonics, reduction of switching noise peaks at the output...

We consider the linear matrix inequality (LMI) problem of H∞ output feedback control for a generalized plant whose input, measured output, disturbance and controlled are scalar. provide an explicit form optimal value. This is unification some results in literature performance limitation analysis. To obtain value, we focus on non-uniqueness perpendicular matrices, which appear LMI problem. use n...
