Abstract
The sampled-data boundary control problem for a longitudinal flexible bat i s formulated as a linens discrete-time control problem in an infinite-dimen sional state space. With zero-order-hold applied to the control channel, th e system is lifted into an infinite sequence of constant control problems, The finite-dimensional approximation of the discrete-time system is control lable-observable if the sampling period satisfies some in-equality constrai nts, which are related to the associated eigenvalues.
