Annotation:

The analysis functions for approximating the surface of the control systems for maximum power point tracking of photovoltaic. A method of creating such systems, which is based on receipt of a control surface (by interpolation and approximation) as a function of two variables: the flux density of incident solar radiation and the operating temperature of the photovoltaic. Grounded and analyzed for the selection of the exponent of the polynomial interpolation approximating experimental data. The estimation errors for the proposed polynomials. A comparison of the approximation discussed in the article, with the previously proposed.

Key words:

maximum power, control surface, interpolation of the experimental data, an approximation polynomial, correction function, the relative error, reference point, a function of two variables, photovoltaic
