Description: Development of physical object mathematical models comparison on example of inertial machine is described. The choice of sampling period of mathematical models output data comparison is implemented due to analysis of their spectral characteristics. Process of spectral characteristics reception by discrete Fourier transformation methods use is described. Testing of the developed method has shown its high efficiency at computer tutoring program execution support and possibility of method application a wide range of technical problems.
Keywords: computer tutoring program, inner loop, competence component, mathematical model, discrete Fourier transformation, spectral characteristic
