Abstract

Presents a solution to the sampled-data H^∞ control problem when the sampling function, the discrete-time controller and the hold function are all design parameters. The generalized sampling and hold functions are constrained to have piecewise impulse and piecewise constant waveforms, respectively. The resulting sampling and hold devices improve the control performance over that based on a zero-order-hold and on an ideal sampler, yet they are readily implementable on digital hardware, in contrast to the unconstrained ones
