The main aim of this paper is to present the possibility to solve one of the main problems of the multilevel inverter drives: the oscillation of the neutral point voltage, in the frame of sliding mode control. Using the robust futures of this control the selection condition for the DC line voltage and the power switch control is received and discussed. It is shown that in the frame of such control...
Sufficient conditions for the state space trajectory of a system of ordinary differential equations (ODEs) to be arbitrarily close to an equilibrium path and for the evolution of the system to be quasistationary are proved using basic topology and mathematical analysis concepts. The conditions are less conservative than previously derived ones based on Lyapunov functions.
A novel sliding mode control for the induction motor (IM) fed by three-level voltage-source inverter (3L-VSI) is proposed in this paper. The ldquoclassicalrdquo results of sliding-mode theory were extended on the actual variable structure system with more then 2m variable structures (m is the control space order) by using an original two-step design procedure that allows separately to use the nonlinearity...
