Interval System analysis of Boost Converter for uncertain load parameter

This paper deals with the characteristics of a Boost Converter in the presence of uncertain load parameter. An Interval System analysis is adopted to evaluate the interval extension of load parameters and frequency response plot of the rational systems is done. A Lead-Lag Compensator is designed which meets the requirement of robust design and the design specification is satisfied over the entire parameter set. Here, all the analyses have been done for continuous conduction mode (CCM) mode of operation and the frequency response is plotted in MATLAB.
