“…The first control technique proposed for experimental validation is based on Hysteresis Band (HB) control, which is a common implementation of sliding mode control (SMC) 17,18 . In Muñoz et al, 19 it was theoretically confirmed that hysteresis band control applied to the BF converter effectively regulates the output, rejects disturbances, and maintains desired periodic orbits within the studied parameter range. However, whether these detailed theoretical findings will hold true in practical implementation remains unknown.…”

The boost‐flyback converter is a type of DC‐DC power converter that allows for efficient step‐up voltage conversion. Despite its potential for achieving high voltage gains, there is a lack of comprehensive analysis and practical implementation of reliable control methods for this converter. To date, only a few control techniques have been thoroughly examined and, more importantly, validated on hardware for this specific converter. In this paper, a comprehensive evaluation of two control techniques is presented, namely, zero average surface (ZAS) and hysteresis band (HB) control, for the boost‐flyback converter. Insights into the performance of these techniques and their applicability in real‐world scenarios are provided by experimental investigation. Experimental results have shown that the ZAS controller, while promising in theory, requires the inclusion of a secondary feed‐forward control loop to achieve accurate regulation of the output and effective disturbance rejection. This finding has highlighted the sensitivity of the ZAS control to measurement noise and the importance of careful consideration when implementing it in hardware. By providing a detailed comparison and insights into the performance of these control techniques, this study contributes to the advancement of control strategies for the boost‐flyback converter and guides future research in this field.

“…This makes it possible to compute the eignvalues of these saltation matrices without performing the full matrix computation. Two non-identity saltation matrices had equivalent diagonal blocks, sliding plastic impact (82) and elastic impact (89). This occurs because the guard surface enforces an equivalent constraint on both position and velocities to be along the guard.…”
