The paper deals with an emerging problem of AC to DC power converters: the establishment of the mean value of the rectified voltage. This is a difficult task due to the nonlinear behavior of the capacitor filter, attached to the rectifiers. Are proposed novel, simplified mathematical models both of the controlled and uncontrolled rectifier, useful in analysis and design stage. A software product is...
The use of fractional operators in automatic control theory is in fact an old concept but also represents a new research field due to the development of effective computational tools. Adaptive controllers and fractional order controllers have been introduced in to order improve the performances and the robustness of the control system. In this study the model reference adaptive control is extended...
