Özet:

 

An observer controller for a buck converter is presented.  A state feedback gain matrix is derived in order to achieve the stability of  the converter and to ensure the robustness of the controller. A load  estimator is designed to estimate the unmeasurable variables and to obtain  the zero output voltage error. A pulse-width modulation scheme is adopted to  obtain the output voltage regulation. In order to improve the transitory  response and dynamic constancy of the converter, the controller parameters  are designed based on the current mode control. The design is evaluated and  verified using MATLAB/Simulink. An experimental set-up is done to evaluate  the controller platform.
