Learning feedback controller design of switching converters via MATLAB/SIMULINK

The application of MATLAB/SIMULINK is developed for simulation and learning feedback controller design of dc–dc switching converters. With the help of its intuitive graphical user interface and some basic circuit theories, the corresponding SIMULINK models of the switching converter circuits can be easily constructed. Students can then use these models to learn and evaluate the closed-loop behavior of the entire system in the MATLAB/SIMULINK environment, after feedback controllers are devised by any classical or modern control theory. The accuracy of this approach is also verified by comparing the simulation results with the responses obtained from a buck-type dc–dc switching converter circuit and existing experimental results [4].
