摘要

In this paper, a nonlinear finite time observer is designed for multicellular converters. The converters topology beneflits from outstanding dynamic performance that dedicates it to mediem voltage and high power application. A new approach of moderation is developed and used for synthesize observers for a three-cell converter with two legs. Three different observation strategies are proposed. More precisely, we show how to design sliding mode and super twisting based observers. The aim is to estimate the capacitor voltages by taking into account the hybrid behavior of the converter. A comparative study with the super-twisting sliding mode observer and H,, observer highlight the efficiency of the proposed strategy. Simulation results are presented in order to illustrate the performance of the proposed approach.
