Sampleddata Sensitivity Operators

Abstract: This paper develops exact, computable
formulas for the frequencygain and L_2induced norm of the
sensitivity operator in a sampleddata control system. With
sampleddata, we refer to a system that combines both
continuoustime and discretetime signals, and which is
studied in continuoustime. The expressions are obtained using
lifting techniques in the frequencydomain, and have
application in performance and stability robustness analysis taking
in account full intersample information.
