This paper presents a real time system identification technique for DC-DC power buck converter applications. In order to achieve real time parameter identification and digital control within a power electronics system, fast convergence speed and low computational burden are necessary. The proposed algorithm, Fast Affine Projection, exhibit both of these requirements. It is applied in the field of power electronics for the first time, and is shown to offer superior performance to alternative techniques such as Least Mean Squares and Recursive Least Squares methods.
