| Abstract |
The Interconnection and Damping Assignment Passivity-Based Control (IDAPBC) is applied phaseindependently to the Modular Multilevel Converter (MMC) in order to overcome dqo-based controlproblems. In addition, an equilibrium point estimator is proposed to determine the time-varyingequilibrium state of the MMC needed as input for the non-linear controller. This control strategyprovides global robust stabilization of the MMC against variations on both its AC and DC sides.Thecontrol + estimator strategy combines both the state-space and energy dynamics models of the MMC. |
