Abstract :
Nonlinear H∞-controller synthesis is presented for time-varying systems via sampled-data measurement feedback. The H ∞-control problem for a nonlinear system with a sampled-data measurement output is shown to be equivalent to the H∞-control problem for a certain nonlinear system with a time-continuous measurement output. Special mathematical tools are developed to straightforwardly derive a local solution of the sampled-data measurement feedback (SMF) H∞-control problem from that of the time-continuous measurement feedback (CMF) H ∞-control problem
