Sliding mode control of the four quadrant quasi-Z-Source DC-DC Converter

Alleviating the right‐half‐plane zero effect on Z‐source converter output voltage regulation using the cascaded sliding mode controller

“…As input voltage and load resistance of the converter may vary, an appropriate controller that guarantees the robustness against uncertainties is required. The sliding mode control (SMC) method, due to the advantage of the variable structure nature, is extensively used for power converters control [7–21]. However, the ideal SMC cannot be employed because of the bounded switching frequency of the converters.…”

“…The stability and robustness of the CSMC were confirmed by simulation and experimental results. In [18], the output voltage of the four‐quadrant characteristic quasi‐ZSC was controlled by a reduced‐order model based on a variable structure control approach. The sliding mode controller guarantees stability as well as robustness against input voltage variation, load resistance, and parameter uncertainty.…”
