Linear matriz inequalities in integrated process design

This work presents a methodology for process design that allows to include certain control conditions at the design stage. The control constraints may be included for the open or closed loop system and they are described by Linear Matrix Inequalities. The problem reduces to a quadratic programming problem where some of the explicit constraints are no linear and the dynamic constraints, associated to the control requirements are faced as an implicit constraint. In this step, another feasibility problem is solved. Performance requirements such as, stability, s-plane pole location, H∞ disturbance rejections are easily included in the approach. In the closed loop design, state feedback control is used. An application to the design of a hydraulic process is featured.
