Popov Theory Based Approach to Digital H(infinity)-Control with Measurement-Feedback for Pritchard-Salamon Systems

摘要

In the paper the authors deal with the digital output measurement-feedback H-infinity control problem for Pritchard-Salamon infinite-dimensional systems with unbounded input and output operators. A discrete Popov theory based solution is given in terms of the solvability of Kalman-Szego-Popov-Yakubovitch systems associated to the equivalent discrete-time, time-invariant system obtained by lifting the T-periodically continuous-time system.
