Discussion on: 'Transfer Matrices and Statistical Analysis of Sampled-data Systems with Continuous Periodic Processes'

摘要

In the paper by Lampe and Rosenwasser a sampled-data feedback system composed of a continuous-time periodic plant and a digital controller is studied, supposing that the period of the plant and that for sampling are coincident. Using the parametric transfer matrix as a main tool, a formula of the H_2 norm is derived in a stochastic setup.rnIt is standard to apply the lifting technique (see [2] and references therein) to the subject of the paper. In this note, we relate results in the paper and the lifting approach. A computational formula for the H_2 norm is also derived.
