Loop Gain under Random Feedback
No full textWe consider the feedback connection of a plant M with a random matrix gain Δ, and study the statistical properties of the loop gain L = MΔ, under the hypothesis that the random feedback A has a unitarily invariant distribution. This setup has interesting connections with two open problems related to the γ-entropy of the plant, and to a probabilistic version of the multivariate Nyquist criterio

No full textIn this paper, randomized algorithms for stability and performance of linear time invariant uncertain systems described by a general M-Δ configuration are studied. On the contrary of the worst-case approach, which is often not tractable in the NP-hardness sense, this problem turns out to be solvable in a probabilistic setting. In particular, efficient polynomial-time algorithms for uncertainty structures Δ consisting of an arbitrary number of full complex blocks and uncertain parameters, real or complex and possibly repeated, are develope
