Resumen:
Design-for-operability is a field of active research in process systems engineering because
of the high economic impact of design on operability. Dynamic operability has been widely
studied by means of the so-called (open-loop) controllability and resiliency indices, which
are mostly based on linearized (Laplace/frequency domains) models of the dynamic systems. In
particular, the minimum singular value of the transfer function matrix is a fair measure of
resilience to disturbances. Among the plethora of approaches to design for dynamic
operability, a multipleobjective formulation between cost and controllability naturally
arises because of the conflicting characters of the two objectives. In this contribution the
cost/minimum-singular-value multipleobjective design problem is solved for the meaningful
reactor-separator-recycle system and two different control strategies. The generation of the
noninferior solution set is performed here within the framework of an eigenvalue
optimization approach.
