The first one is a continuous crystallizer, see Section 8.1, and the second one is an open-channel for hydroelectricity generation, see Section 8.2. Both systems are described by Partial Differential Equations (PDE), resulting in irrational transfer functionss. Contents 7.1 Preliminary: data-driven closed-loop stability assessment and enforcement
