Moment matching for linear systems - overview and new results ⋆

چکیده
The problem of proposing a framework for linear moment matching is tackled. It is possible to define five notions of moments, i.e., two from a complex ”s-domain” point of view and three from a time-domain point of view. Based on these notions, reduced order models that achieve moment matching are obtained. This paper sets the basis to develop the theory of model reduction by moment matching for nonlinear systems.

In this paper a destriping technique is proposed for pushbroom-type satellite imaging systems. This technique is based on Moment Matching algorithm and assumes a linear response for each detector of imaging system. In the most of the works in this field, the offset parameter in detectors’ response is neglected and images are corrected using only an estimation of gain parameter. Proposed m...
متن کاملNon-Linear Behavior of New (FSFN) Moment Resisting Connections in Comparison to the Existing KBB Connections in Steel Frames
After Northridge (1994) and Kobe (1995) earthquakes, several studies have been conducted to improve the seismic performance of steel structures. In this investigation, new steel moment-resisting connections (FSFN) developed by the authors, were studied by the non-linear numerical analysis. These connections were single-sided beam-to-column assemblies that are representative of exterior beam-to-...
متن کاملFamilies of moment matching based, structure preserving approximations for linear port Hamiltonian systems
In this paper we propose a solution to the problem of moment matching with preservation of the port Hamiltonian structure, in the framework of time-domain moment matching. We characterize several families of parameterized port Hamiltonian models that match the moments of a given port Hamiltonian system, at a set of finite interpolation points. We also discuss the problem of Markov parameters ma...
متن کاملA short overview of the electrical machines control based on Flatness-technique
Optimal linear controllers and high computational non-linear controllers are normally applied to control the nonlinear systems. Flatness control method is a control technique for linear systems as well as nonlinear systems by static and dynamic feedback namely as endogenous dynamic feedback. This method takes into account the non-linear behavior of the process while preventing complicated compu...
متن کاملA survey on model reduction of coupled systems
In this paper we give an overview of model order reduction techniques for coupled systems. We consider linear time-invariant control systems that are coupled through input-output relations and discuss model reduction of such systems using moment matching and balanced truncation. Structure-preserving approaches to model order reduction of coupled systems are also presented. Numerical examples ar...
