Comparison of nonlinear control techniques applied to SEPIC and CUK converters with reduced modeling and hybrid solutions

This paper presents a study and comparison of nonlinear control techniques applied to SEPIC and CUK converters with reduced modeling and hybrid solutions based on boost converter. Three nonlinear control techniques — state feedback linearization (SFL), passivity based control (PBC) and interconnection and damping assignment passivity-based control (IDA-PBC) has been validated experimentally using HIL simulation for boost and SEPIC converters. Simulation results are also presented for these converters and control methods.
