Non-linear controller applied to boost DC-DC converters using the state space average model

Abstract

This work aims to present a methodology to use the large signal state space average model of the DC-DC converters for high performance controllers design. The design using classic control theories need the SISO transfer function. Often, these functions are obtained using linearization around the point of operation. It reduces the range of operation to the designed controller with the expected performance. Also, the presented controller showed to have high disturbance rejection dependent on the sensors used. The presented controller is described, simulated and experimentally confirmed.
