Abstract:
This paper presents an exact static error dynamics passive output feedback controller to regulate the output voltage of the DC-to-DC power converter Cuk type; this controller is obtained from the error dynamics of the nonlinear average model of the converter. In order to compensate the effects of sudden changes in the load resistance, the desired reference variables for the regulation task are calculated using the estimated load value obtained via an algebraic estimator. The results are validated in an experimental laboratory setup.
