On the identification of functional differential systems with aftereffect (Q1293583)

The problem of the identification (parameter determination) of functional differential systems with aftereffect from indirect measurement of input and output of the object is considered. \[ \dot x(t)= \sum^M_{i=1} \varphi_i(w) A_i(t, C^t_\theta x)+ \sum^N_{j=1} \Psi_j(w) B_j(t, C^t_\theta v),\;x(\theta)= \alpha. \] The basis of the approach is the modification of the method of least squares and the solution of the corresponding system of algebraic equations. It is worth mentioning the very complicated language of the work.
