A Comparison between Classical and Advanced Controllers for a Boost Converter

Abstract

DC-DC switching converters are well known for their versatility with wide range of applications. Such demanding applications are always required fixed voltage for of any changes on input or load side. Here, three different control topologies such as Classical PID controller, Sliding Mode Controller (SMC) and Internal Model Controller (IMC) have been implemented for achieving better performance and voltage regulation for Boost converter. In this work, the converter performances with PID controller is compared with IMC and SMC. The closed-loop performances of converter with these different control algorithms are compared in load and reference voltage disturbances. IMC behaves like a superior controller compare to other control algorithms for its better steady-state and transient responses. Here, computational results are reported for the verification purpose but the practical implementation is going on and that may be future scope of this presented work.
