Two approaches are presented in this paper to estimate the state of an induction motor and detect faults: a geometric approach, assuming only that the perturbations belong to known bounded sets with no hypothesis on their distributions inside these sets, and a stochastic approach by Kalman filtering. Recursive and explicit algorithms are presented and(More)
Proving the stability of a discrete{time implementation of the standard eld{oriented control (FOC) of induction motors is an open problem of great practical and theoretical signiicance. In a recent paper a modiication to the FOC was introduced to rigourously establish global asymptotic speed regulation and rotor ux norm tracking for current{fed machines. In(More)

This paper highlights the energy errors made for the design of supercapacitors used as a main energy source. First of all, the paper presents the two definitions of capacitance of a capacitance-voltage dependent material. The number of supercapacitors is important for the application purchasing cost. That is why the paper introduces an analytical model and(More)
