چکیده
A discrete-time sliding mode controller is presented for DC-DC converters. A criterion for the existence of the sliding surface is derived based on the LMI technique combined with the Lyapunov method. In addition, the design of sliding mode control is presented according to the reachability condition. The control law can effectively constrain the input disturbance and reduce the effects from the parameter variations while the bounds of the uncertainties are unknown. Finally, simulation results show the feasibility and effectiveness of the proposed method Streszczenie. Zaprezentowano kontroler ślizgowy o czasie dyskretnym do przekształtników DC-DC. Kryterium obecności powierzchni ślizgowej jest wyprowadzone bazując na technice LMI i metodzie Lapunowa. (Dyskretne sterowanie ślizgowe dla przekształtników DC-DC z niepewnościami). x
