Autoimmune encephalitis: chasing a moving target

In this paper we propose a novel algorithm based on linear matrix inequalities for the design of distributed controllers and state estimators for large-scale systems inspired by linear quadratic regulators and Kalman filters, respectively. With respect to similar state-of-the art methods, the scheme proposed here allows to reduce the conservativeness due to the approximations used for the covariance distributed iterative computation. The theoretical properties of the proposed scheme are thoroughly investigated. The controllers and observers obtained using the proposed approach are applied to a simulated dynamical system and their performances are thoroughly compared to those obtained with state-of-the-art schemes, showing the potentialities of the scheme.

Automated summary

In this paper, a novel algorithm based on linear matrix inequalities is proposed for the design of distributed controllers and state estimators for large-scale systems. The algorithm is inspired by linear quadratic regulators and Kalman filters. Compared to similar methods, the proposed scheme reduces the conservativeness caused by the approximations used for the covariance distributed iterative computation. The theoretical properties of the proposed scheme are thoroughly investigated, and its performances are compared to state-of-the-art schemes, demonstrating its potential.
