Comparsion of Different Methods for Controlling DC-DC Converters in Constant Current Mode

The paper compares different control methods for DC-DC converters operating in constant current mode. The following are considered: a classic controller based on a PID controller, a neural network controller, a predictive controller model, and a linearized controller. Controller synthesis was performed based on a model in the MATLAB/Simulink environment. The purpose of the research is to place the controllers under the same destabilizing factors and to evaluate their performance. The results presented here are from a study of a Buck DC-DC converter, but they can also be interpreted for the entire class of devices. On the other hand, they are also useful in Power Electronics training, and especially in the control of power electronic devices and systems.
