Partial eigenvalue assignment problem of linear control systems using orthogonality relations [PDF]
Acta Montanistica Slovaca, 2006 The partial eigenvalue assignment is the problem of reassigning a part of the open-loop spectrum of a linear system by a feedback control, leaving the rest of the spectrum invariant.

Design of Marx generators as a structured eigenvalue assignment [PDF]
Automatica, 2014 We consider the design problem for a Marx generator electrical network, a pulsed power generator. The engineering specification of the design is that a suitable resonance condition is satisfied by the circuit so that the energy initially stored in a number of storage capacitors is transferred in finite time to a single load capacitor which can then ...

Decentralized PI Controller Design by Eigenvalues Assignment
IFAC Proceedings Volumes, 2000 A procedure for designing proportional, integral,and derivative (PID) decentralized controllers based on eigenvalues assignment techniques is presented. The advantage of such a procedure is the extra flexibility offered where it allows one to govern the rate of decay and achieve certain performance characteristics besides the well-known properties of ...

Phase Field Failure Modeling: Brittle‐Ductile Dual‐Phase Microstructures under Compressive Loading
Advanced Engineering Materials, EarlyView.The approach by Amor and the approach by Miehe and Zhang for asymmetric damage behavior in the phase field method for fracture are compared regarding their fitness for microcrack‐based failure modeling. The comparison is performed for the case of a dual‐phase microstructure with a brittle and a ductile constituent.
