CONSTRUCTION OF APPROXIMATION MODELS OF OBJECTS WITH DISTRIBUTED PARAMETERS
Keywords:
transcendental and irrational transfer functions, objects with distributed parameters, algorithm, interpolation and variational methods, approximation model.Abstract
The article is devoted to the development of an algorithm for the numerical implementation of transcendental and irrational transfer functions based on interpolation and variational methods. Attention is paid to the possibility of obtaining effective and simple computational equations for the most common transcendental and irrational expressions in practice. The method of modeling by the characteristics of imaginary frequencies, the use of the z-transform and the method of nonlinear approximation for modeling objects with distributed parameters are considered.
