Improving the Accuracy of the DC-DC Converter using Disturbance Estimator

摘要

This study discusses the design of a discrete-time controller for self-tuning that takes into consideration random disturbances that effect on the boost DC-DC, this controller implements the Generalized Minimum Variance Control (GMV) with disturbance estimator. The GMV method is based on the input/output measurements and holds the output voltage as stable as possible in spite of the parameters variations while the disturbance estimator increases the accuracy. Finally, we verify the control method by digital simulation to show the performance and the effectiveness of the controller added to the boost DC-DC converter.
