A New Design of Robust Digital Controller for Dc-dc Converters
نویسندگان
چکیده
Robust DC-DC converters which can cover extensive load changes and also input voltage changes are needed. In this paper, we propose a new method for designing good approximate 2-degree-of freedom (2DOF) digital controller which makes the control bandwidth wider, and at the same time makes a variation of the output voltage very small at sudden changes of resistive load. The proposed approximate 2DOF digital controller is actually implemented on a DSP and is connected to a DC-DC converter. Experimental studies demonstrate that this type of digital controller can satisfy given specifications. Copyright c °2005 IFAC
