چکیده مقاله:
In this paper a Fuzzy sliding mode control scheme with the sliding surface as input is proposed in order to improve the robustness and performance of a buck-boost DC-DC converter. The simulation results show that the proposed controller overcomes the chattering problem and it is proved to be robust for the cases of the load and input voltage variations. However, the sliding mode controller here is of the PI loop does not suit all operating conditions. More accuracy can be achieved by modifying fuzzy rule base and membership functions. The introduced control system is simulated by MATLAB/SIMULINK.
