Conceived by Count Jacopo Francesco Riccati more than a quarter of a
millennium ago, the Riccati equation has been widely studied in the
subsequent centuries. Since its introduction in control theory in the
sixties, the matrix Riccati equation has known an impressive range of
applications, such as optimal control, H? optimization and robust
stabilization, stochastic realization, synthesis of linear passive
networks, to name but a few. This book consists of 11 chapters surveying
the main concepts and results related to the matrix Riccati equation,
both in continuous and discrete time. Theory, applications and numerical
algorithms are extensively presented in an expository way. As a
foreword, the history and prehistory of the Riccati equation is
concisely presented.
