....1109/STAB49150.2020.9140662 An approach based on Volterra polynomials with vector input signals has been developed for numerical modeling of the process of controlling the dynamics of an ""input-output""type object. The nonparametric identification problem is considered as a conjugate one with respect to the deconvolution problem. The paper focuses on a new algorithm of identifying Volterra polynomials of the second degree that is based on the active experiment by the test sets of ...

Thermal Transients in District Heating Systems // Energy. Vol.184. 2019. P.22-23. DOI: 10.1016/j.energy.2018.01.049 Heat fluxes in a district heating pipeline systems need to be controlled on the scale from minutes to an hour to adjust to evolving demand. There are two principal ways to control the heat flux - keep temperature fixed but adjust velocity of the carrier (typically water) or keep the velocity flow steady but then adjust temperature at the heat producing source...

Results of the calculations for reference mathematical systems are presented to illustrate the applicability domains of the integral models on the basis of the quadratic Volterra polynomials. The software "Dinamika" intended for the identification and modeling of reference heat and power facilities is demonstrated. входит
