STUDY OF DISCRETE GLOBAL-SLIDING MODE CONTROL FOR SWITCHING DC-DC CONVERTER

摘要

Discrete global-sliding mode (SM) control of switching DC-DC converters is presented in this paper. The existence and stability conditions of quasi global-sliding mode are proposed. The design method for the discrete global SM controller is studied and applied to Buck converter with global-sliding mode control. Computer simulation and experimental results verify the validity of the theoretical analysis.
