【Abstract】 Discusses the robust stability of the sampling system for a class of non structural perturbation models in time domain, establishes the sufficient condition for the robust stability for the sampling system under the control of the optimal digital controller and gives the new upper robust stability bound and concludes from the analysis of an example, that the conservativeness of the results proposed is significantly reduced, and the sampling period is a crucial design parameter.更多还原
