Development of Kalman Filter Based Discrete PID Controller for DC-DC Converter

Abstract

In industrial settings, PID-Regler (Proportional Integral Derivative) most frequently utilised. to obtain the desired performance of the system. To get the PID controller’s ideal parameters, several tuning techniques have been devised. First PID is tuned with the Ziegler-Nichols method to obtain initial parameters and followed with an auto-tuning algorithm. However, the majority of PID auto-tuning techniques are created in ideal conditions. As a result, when noise is present, the control system will not operate at its best. Electrical movements, electronic components, or any other noise source may produce this noise.This work presents a self-tuning method based on the Kalman filter approach designed and put into practise on a DC-DC converter. The outcomes of the simulation show that the efficiency of the PID+ Kalman filter incorporated DC-DC converter is more optimal than the simple PID auto-tuning of the PID controller.
