Abstract
In this paper, a new control strategy of a multicellular converter (three cells) is proposed in order to drive a DC machine, there were two main goals to achieve: i) ensure a suitable distribution of flying capacitors voltage which implying the regulation of voltages across capacitors, ii) regulating DC motor velocity to a desired level. The proposed system is described by 4th order nonlinear mathematical model. To stabilize the global system and realize the above objectives, a controller based on differential flatness approach is synthesized in order to control this system. The simulation results have been performed through Matlab/SimPowerSystems environment and show that the designed controller meets its objective.
