Abstract :
In this paper, we have applied Quantitative Feedback Theory (QFT) to design a compensator for a Boost Converter in Continuous Conduction Mode. Being an advanced robust control technique, QFT is able to meet all the closed loop specifications of the system and make it insensitive to parametric variations, load current perturbations and duty ratio variations for a given set of plants. The design and analysis of voltage-mode controlled Boost converter are done using Matlab® software and satisfactory results are obtained.
