Data-driven Structured Realization

چکیده
We present a framework for constructing structured realizations of linear dynamical systems having transfer functions of the form C̃( ∑K k=1 hk(s)Ãk) −1B̃ where h1, h2, ..., hK are prescribed functions that specify the surmised structure of the model. Our construction is data-driven in the sense that an interpolant is derived entirely from measurements of a transfer function. Our approach extends the Loewner realization framework to more general system structure that includes second-order (and higher) systems as well as systems with internal delays. Numerical examples demonstrate the advantages of this approach.

Ethical Theory and Educational Effectiveness
The missing link in the theories of normative ethics is the study of the extent of their real impact on the moral education of individuals and societies. Existing moral theories can be divided into act-driven theories, agent-driven theories, and combined and bifocal theories. Each of these theories has shortcomings in relation to the issue of moral education, some of which, like the act-driven ...

متن کاملRealization and identification of autonomous linear periodically time-varying systems
Subsampling of a linear periodically time-varying system results in a collection of linear time-invariant systems with common poles. This key fact, known as “lifting”, is used in a two step realization method. The first step is the realization of the time-invariant dynamics (the lifted system). Computationally, this step is a rank-revealing factorization of a block-Hankel matrix. The second ste...
متن کاملData-driven interpolation of dynamical systems with delay
We present a data-driven realization for systems with delay, which generalizes the Loewner framework. The realization is obtained with low computational cost directly from measured data of the transfer function. The internal delay is estimated by solving a leastsquare optimization over some sample data. Our approach is validated by several examples, which indicate the need for preserving the de...
متن کاملAMSI: An Automatic Model-Driven Service Identification from Business Process Models
The evolution of software engineering has passed through various paradigms; including structured programming, object oriented programming, component-based approaches and in recent years service-oriented computing. One of the key activities needed to develop a quality service oriented solution is the specification of service model. The majority of existing methods for service model specification...
