MRAC Control Based on the LYAPUNOV Function for DC-DC Buck Converter without Mechanical Sensor

Abstract: In this article, we have studied the Model Reference Adaptive Control (MRAC) of the DC-DC Buck converter without mechanical sensor. One of the commands uses the PI controller and the second is based on the LYAPUNOV function. The stability of the command is proven. The proposed observer estimates the current of the inductor as it has a single tuning parameter θ. The simulation results, with the SIMULINK/MATLAB software, of control based on the LYAPUNOV function and the proposed observer are very satisfactory.
