DUALITY FOR DIFFERENTIAL-DIFFERENCE SYSTEMS OVER LIE GROUPS

In modern mathematical systems theory, there exist two consistent ways of defining and describing a linear system: (i) in the behavioral approach, a linear system is the kernel B of a matrix-valued operator R in a power of a signal space W ; (ii) in…

Lower bounds on the mean square error derived from mixture of linear and non-linear transformations of the unbiasness definition

It is well known that in non-linear estimation problems the ML estimator exhibits a threshold effect, i.e. a rapid deterioration of estimation accuracy below a certain SNR or number of snapshots. This effect is caused by outliers and is not captured…

Comparative Study of Switched Reluctance Motors Performances for Two Current Distributions and Excitation Modes

This paper presents a 3-phase, 6-slot, and 4-pole Mutually Coupled Switched Reluctance Motor (MCSRM 6/4) with new current distribution. This kind of SRMs has both the merits of conventional SRMs and Fully Pitched SRMs, i.e. shorter end-windings and…

Comparison between Lead-Acid and Li-Ion Accumulators in Stand-Alone Photovoltaic System Using the Gross Energy Requirement Criteria

The high economic (and energetic) cost of storage accumulator system is still limiting the proliferation of SAPV system. Presently, due to its technical maturity and its low economical investment cost, the storage system universally used in SAPV…
