Design of resilient processing plants—III: A general framework for the assessment of dynamic resilience

Abstract With increased process integration it has become very important to evaluate and compare the dynamic operability characteristics (dynamic resilence) of alternate designs. Based on recent results in multivariable frequency response theory a new framework is developed for this purpose. It is shown that dynamic resilence is determined by characteristics inherent in the system and that it is independent of the imposed controller structure and type. This gives the new method considerable intuitive appeal and allows it to avoid the lengthy optimization procedures which are typical for the previously published techniques.
