Three-Phase Power Converter Stabilization via Total Energy-Shaping

The three-phase power converter mathematical model expressed in Park coordinate is represented in PCH (port controlled Hamiltonian) system form, which is able to manage so much constant load as variable; the controller design for the converter is carried out by the IDA-PBC (interconnection and damping assignment-passivity based control) technique, assigning to the closed loop dynamics to a desired energy function, modifying in a suitable form the interconnection and damping matrices. The control objectives are directed to maintain the DC regulation voltage at the output converter even with variable load, while the input power factor stays unitary; at the same time, the controller is robust to changes in the input voltage
