The identification problem for defining the parameters of discrete dynamic system
An identification problem is considered. It allows to determine the parameters of dynamic system in the discrete case. First, the nonlinear discrete equation is linearized by the method of quasi-linearization. Then, the quadratic functional and its gradient are derived using the statistical data. A...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | An identification problem is considered. It allows to determine the parameters of dynamic system in the discrete case. First, the nonlinear discrete equation is linearized by the method of quasi-linearization. Then, the quadratic functional and its gradient are derived using the statistical data. A calculation algorithm is proposed to the solution of problem in hand. It is shown on an example that the statistical value of the coefficient of hydraulic resistance differs from the obtained value on the order 10⁻⁴. It shows an adequacy of the mathematical model. |
