Resumen de Power-controlled Hamiltonian systems: Application to electrical systems with constant power loads

Pooya Monshizadeh, Juan E. Machado, Romeo Ortega, Arjan van der Schaft

• We study a type of port-Hamiltonian system in which the controller or disturbance is not applied to the flow variables, but to the systems power balance equation—a scenario that appears in many practical applications. A suitable framework is provided to model these systems and to investigate their shifted passivity properties, based on which a stability analysis is carried out. The applicability of the results is illustrated with the important problem of stability analysis of electrical circuits with constant power loads.
