Abstract :
The multicell converters introduced more than ten years ago. They are capable to handle higher voltage ratings with lower rating switches. Different active control strategies have been introduced to control the state variables of converter. In this paper a new online optimal controller based on the discrete nonlinear model of multicell inverters will be presented. The optimal feedback will control the state variables in a very fast and efficient manner. The main idea is based on the "tracking problem" of reference signals by state variables. Simulation results and the theoretical details will be presented in the next sections.
