ABSTRACT

We demonstrate that the problem of recovering state vector of nonlinear and generally nonstationary dynamic systems is reduced to necessity of ensuring robust stability of extended system by a proper choice of control law of the recovering system. Sufficient conditions of robust stability “inside domain” are determined on the basis of reducing nonlinear functions to quasilinear form. Constraints in the form of inequalities, fulfillment of which ensures solution of the problem of state vector recovery, are derived.
