This work analyses the performance of Discrete PID controller for Boost converter. The purpose of designing discrete time controller is to attain higher voltage regulation in output, excellent energetic performances and good efficiency in a converter. In this method, the conversion from continuous to discrete is based on time domain bilinear transformation technique, so that the errors in the converter can be avoided. The feedback from the digital controller can continuously tunes the compensator parameters to attain the converter specifications. This control provides a whole compensation, which additionally develops the sturdiness and stability of the closed loop system. The discrete PID controlled boost converter has been simulated using MatLAB / Simulink and the experimental results have been presented to reveal the success of the controller using LabVIEW.
