Taschenbuch. Zustand: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Descriptor system is mixed of differential and algebraic equation which has a large number of applications. This class of systems may be classified as implicit, semi implicit and may also be called singular system. This book deals with solvability and some qualitative properties like stability, consistency, regularity and stabilization for non-linear descriptor systems with open(closed) loop feedback controller. A non-classical variational approach was developed for solving linear time varying(invariant) descriptor systems. Logarthmic norm approach has modified for some class of this system to ensure the stabilizability of some sense.…

Taschenbuch. Zustand: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - This work studied some classes of linear time-varying and constant coefficients composed of descriptor operator equations with consistent initial conditions as well as consistent boundary conditions using suitable Hilbert spaces. The composed descriptor operator is standing for coupled pair of differential-algebraic operator equations together with the consistent initial operator or consistent boundary operator defined in this work on reflexive Cartesian Hilbert spaces.We have proved that this composed descriptor operator is extendable to closed bounded densely defined operator, and has adjoint as well as second adjoint with natural extension property. Due to the importance of the symmetry of this operator for solvability, the symmetry has been also discussed and developed with respect to Cartesian bilinear form using the functional (Variational) approach. This approach is based on finding a suitable functional form whose critical point is the solution of the proposed problem (composed descriptor operator) and the solution of the proposed problem is a critical point of the obtained Variational functional.…
