Abstract

This tour of four puzzles is to highlight fundamental and surprising open problems in linear systems and control theory, ranging from system identification to robust control. The first puzzle deals with complications caused by fragility of poles and zeros in standard parameterizations of systems due to unavoidable parameter inaccuracies. The second and the third puzzle are concerned with difficulties in generalizing robust H ∞ control theory to realistic persistent signal setups. Surprisingly it seems very difficult to generalize the theory to such setups and simultaneously keep the terminology robust H ∞ control intact. These puzzles have implications also to model validation. The fourth puzzle, due to Georgiou and Smith, deals with difficulties in doubly-infinite time axis formulations of input-output stabilization theory.
