“…, p − 1} is observable according to the current measurement. As the observability is related to the mode m, the capacitor voltages are not observable through the same mode m, so it is not possible to apply a full rank observer on the hybrid model (8). The solution proposed by [18] is to break down the model into non linear sub-models where each one describes the dynamic of one voltage capacitor.…”

The requirement of high voltage-power level for many applications like the energy conversion system give rise to use a structure of a multilevel converter like the multicell series converter. To benefit as much as possible from this power converter an appropriate voltage distribution for each cell must be performed, hence the need to estimate this voltages. This paper aims to design a minimal single linear functional observer for a multicell series converter to estimate the capacitor voltages. Based on its hybrid model, an observability study prove the ability to estimate this capacitor voltages. Also a linear functional observers are proposed using a direct procedure without solving the Sylvester equation and based on an operation mode classification approach. Simulations of four-cells multicell converter are given in order to check the efficiency of the converter's hybrid model and the performance of the proposed minimal single linear functional observers.Recently, [9] detailed the design of the functional observer for switched discrete system.
