WebTutorial: Reducing an LTI system using balanced truncation¶. Here we briefly describe the balanced truncation method, for asymptotically stable LTI systems with an invertible \(E\) matrix, and demonstrate it on the heat equation example from Tutorial: Linear time-invariant systems.First, we import necessary packages, including BTReductor. WebEstimator for sigma squared Description. Returns maximum likelihood estimate for sigma squared. The “.A” form does not need Ainv, thus removing the need to invert A.Note that this form is slower than the other if Ainv is known in advance, as solve(.,.) is slow..
