Input-Output Discrete Integral Sliding Mode Controller for DC-DC Buck Converter

Discrete-time integral sliding mode control is widely applied using state space model. Therefore, some systems are known only by their input-output measurement. In this work, a discrete-time integral sliding mode controller (DISMC) based only on Input-Output model is presented. The proposed approach is developed and considered as a new method for voltage controller of electronic power systems, such as DC-DC buck converter. The simulation results prove the efficiency of the proposed DISMC.
