Sliding Mode Fuzzy Observer for DC-DC Converters

In this work the design of a fuzzy observer with sliding modes for DC-DC power electronics converters is presented. The observer is based on a fuzzy Takagi-Sugeno model having two variable premises, inductor current and capacitor voltage. The observer is validated in simulation with a mathematical software analyzing the observer's convergence in the transient state, under disturbances in the input voltage and in the load.
