On preserving passivity in sampled-data linear systems
Document typeExternal research report
Rights accessOpen Access
Passivity is a well know phenomenon in several engineering areas. Due to its interesting properties, it is used in several areas of control engineering. Generally, this property is lost under direct discretization. In this work a new methodology which allows to preserve continuous-time passivity is presented. This methodology is based on choosing a proper output, which preserves the passivity structure, while keeping the continuous-time energy function. Analytic formulation and numerical examples, both open and close loop, are provided in the paper.
