“…• Complements the FLC control and allows load estimation given by (26), being more robust to load disturbances; • Given the caveats imposed by (22), the adaptive control law works for both conduction current modes (DCM and CCM); • Neglecting the current measurement of the intermediate inductor L 2 ; this characteristic is motivated by the analysis discussed in the following section.…”

Abstract:In this paper, we propose adaptive nonlinear controllers for the Single-Ended Primary Inductance Converter (SEPIC). We also consider four distinct situations: AC-DC, DC-DC, Continuous Conduction Mode (CCM) and Discontinuous Conduction Mode (DCM). A comparative analysis between classic linear and nonlinear approaches to regulate the control loop is made. Three adaptive nonlinear control laws are designed: Feedback Linearization Control (FLC), Passivity-Based Control (PBC) and Interconnection and Damping Assignment Passivity-Based Control (IDAPBC). In order to compare the performance of these control techniques, numerical simulations were made in Software and Hardware in the Loop (HIL) for nominal conditions and operation disturbances. We recommend adaptive controllers for the two different situations: Adaptive Passivity-Based Feedback Linearization Control (APBFLC) for the PFC (Power Factor Correction) AC-DC system and IDAPBC-BB (IDAPBC Based on Boost converter) for the regulator DC-DC system.

A linear-to-nonlinear translator is proposed herein and applied to the boost converter to improve the operating performance of the boost converter all over the input voltage range. The proposed translator is inserted between the PID controller and the main power stage such that the PID controller considers the behavior of the boost converter to be quasi-linear, thereby suppressing the effect of nonlinear behavior of the boost converter on the PID controller. In this paper, some experimental results are provided to demonstrate the effectiveness of the proposed control scheme.
