Nonlinear control of DC-DC switching regulators
DC-DC switching regulators are highly nonlinear systems which are subjected to significant variation in the line voltage and load, uncertainty in the circuit parameters and perturbations in switching times; such that the classical linear control are unable to achieve specified objectives and desired performance. These considerations in conjunction with increasing demand for high quality DC-DC switching regulators has necessitated more effective and precise methodologies in control design for such systems. In this paper, the input-output feedback linearization technique as a powerful nonlinear control tool is used to obtain a suitable controller which guarantee satisfactory operation of the system under realistic operating conditions. The resulting controller is shown to minimize the effect of disturbances and achieve acceptable regulation. The potential superiorities of the proposed method over classical methodologies are also discussed.

Citation countsare sourced monthly fromand citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
