Stability and performance recovery within discretized non-linear control systems

By Guido Herrmann, Sarah K. Spurgeon and Christopher Edwards

Abstract

Metadata only entryIn this paper, a closed-loop fast sampling analysis of a discretized (emulated) continuous-time controller in a sampled-data environment is presented. The analysis involves a general weighted version of the Lp-norm. This allows a qualitative and quantitative stability and performance analysis for an emulated controller. Several examples are used to show the relevance of these results for the analysis of sampled-data implementations and the computation of quantitative upper limits on the sampling period to achieve recovery of stability and performance
