Model reduction → when we have a model but it is too large to be used in a control, so we are going to compress the model into a smaller one that captures the general dynamic of the system. In this lecture, we discuss the overarching goal of balanced model reduction: identifying key states that are most jointly controllable and observable, to capture the most input—output.

To transform a realization into a balanced form, we require the n × n coordinate trans formation matrix t from balanced coordinates xb to the given coordinates x (x = t xb) such that the observability and controllability gramians are diagonal and equal. In this paper we formulate and solve the problem of constrained optimal model reduction. using a data driven approach we determine an estimate of the moments and of the transient response of a possibly unknown system. In this paper, we explore the role of tensor algebra in balanced truncation (bt) based model reduction/identification for high dimensional multilinear/linear time invariant systems. In this note, we explore a middle ground between data driven model reduction and data driven control. in particular, we use snapshots collected from the system to build reduced models that can be expressed in terms of data.

Model reducer provides an interactive tool for performing model reduction and examining and comparing the responses of the original and reduced order models. to approximate a model by balanced truncation in model reducer: open the app, and import an lti model to reduce. Balanced truncation is a model reduction technique. the idea is to develop an approximate surrogate model of a complex system that has far fewer state variables. In this lecture, we introduce the eigensystem realization algorithm (era), which is a purely data driven algorithm to obtain balanced input—output models from impulse response data. This review discusses a range of techniques for analyzing such data, with the aim of extracting simplified models that capture the essential features of these flows, in order to gain insight into the flow physics, and potentially identify mechanisms for controlling these flows.
