The problem is first formulated as a sampled-data $H^{\\infty}$ control problem with a generalized sampler and a generalized hold, which can be reduced to a discretetime $\\ell^2$-induced norm minimization problem. Taking account of the implementation of the generalized sampler and hold, we adopt the filter-sampler structure for the generalized sampler, and the uspampler-filter-hold structure for the generalized hold.
