Modular Multilevel Converter (MMC) is becoming increasingly popular with the development of HVDC connections and, in the future, with the integration of Multi Terminal DC grids. A lot of publications have been published about this topology these last years since it was first proposed. Few of them are addressing explicitly the two different roles that are held by this converter in an HVDC link: power...
This paper proposes the energy based controller incorporated with fuzzy neural network compensation (ECFNNC), which is used to swing up the Aapdubot and rise it to its uppermost unstable equilibrium position. Firstly, for the known dynamics model of the three-link arm, the energy based controller is designed. In the energy based controller, the singularity is successfully avoided by constructing an...
Two different control schemes suitable for closed-loop and open-loop operation of an overhead crane system are proposed. The first controller is a passivity based closed-loop PD controller suitably extended by a coupled-dissipation nonlinear term in order to provide substantial reduction of load oscillations. As it is proven in the paper, this additional controller increases the damping of the system...
