Statistical analysis of differential-difference systems (Q1110480)

The paper deals with a hybrid dynamic system which is described by interrelated systems of nonstationary differential and difference equations in the presence of noise. A general formulation of the problem of statistical analysis of the accuracy of the system is presented. Its solution is given in case of nonrandom time quantizations with a dequantifier of any order and in the case of random time quantizations with a zero-order dequantifier. Differential equations for the distribution moments and the correlation matrices are presented. Finally, an example is considered.
