Selection of reduction parameters of Rational Krylov methods for complex MIMO LTI models using evolutionary algorithm

This paper presents the determination of optimal reduction parameters for complex models of the Rational Krylov methods with using Evolutionary Algorithm. The presented algorithms facilitate a precise reduction of linear time invariant, multi-input and multi-output models. The elaborated algorithms are particularly significant for MIMO models, for which the individual channels differ significantly from each other. The prepared algorithms have been applied for the reduction of the subsystems models of a BP-1150 steam boiler.
