Discrete -Time Controller for Transient & Steady-State Response Improvement of DC-DC Boost Converter

Abstract

DC-DC Boost Converters are nowadays extensively used in the electrical and electronic industries. They boost-up the input side voltage while the current steps down from input to output. This simple circuit is the need of almost every electronic circuit, new generation Electric vehicles, medical equipment, textile industry, space systems, etc. But despite of all the merits and uses, it offers a destabilized output response with overshoot and steady-state error. To overcome this issue and to improve the transient and steady-state response of DC-DC Boost Converter, a PID controller has been designed which is not only improves the dynamic response of the converter but also increases the stability and efficiency of the system. To further implement the system according to the needs of new technology, PID controller has been designed digitally/discretely. A low-cost micro-controller board, Arduino NANO is used for controlling while MATLAB-Simulink is used to tune the parameters of PID controller.
