Cover Story: This work addresses switching structured linear systems, a class of dynamic systems whose existing links between the state, input, and output variables have unknown numerical values and are subject to change according to an exogenous signal. Geometric methods and tools developed to solve control and observation problems stated for this class of structured linear systems are presented. In particular, this work delves into the notions of invariance, controlled invariance, and conditioned invariance and their use in the statement and proof of conditions for the solvability of control and observation problems. The fundamental concepts and main results are explained using handy examples, with visual aid provided by directed graphs. View this paper
