Active power is transferred from the auxiliary winding to the main winding and injected back in the grid. Using the steady-state equivalent circuit of the motor, this power reversal phenomenon is studied. Formulas, describing the motor behaviour, allow to simulate the power reversal phenomenon using MATLAB. (6 pages)

Unlike with classical Liapunov theory, the time derivative of the V-function, taken along solutions of the system, may have positive and negative values. It is shown that the proposed condition is useful for the study of uniform asymptotic stability of homogeneous systems with order τ>0. In particular, it is established that asymptotic stability of the averaged homogeneous system implies local uniform asymptotic stability of the original time-varying homogeneous system. This shows that averaging techniques play a prominent role in the study of homogeneous-not necessarily fast time-varying-systems

As an application of this duality principle, stability and boundedness results for negative order homogeneous differential equations are obtained, starting from known results for positive order homogeneous differential equations. 1 Introduction Homogeneous vectorfields are vectorfields possessing a symmetry with respect to a family of dilations. They play a prominent role in various aspects of nonlinear control theory. See, for example, [1, 2, 5, 8] for some applications in feedback control. Recently, interesting results have been obtained for the particular class of positive order homogeneous differential equations: Peuteman and Aeyels [9] have proven that a timevarying positive order homogeneous differential equation is asymptotically stable if the associated averaged differential equation is asymptotically stable; Peuteman, Aeyels and Sepulchre [10] have proven that a time-varying positive order homogeneous differenti...
