Predictive Functional Control of Unstable Processes

Application of predictive functional control (PFC) has been very successful on many processes, however, application to unstable open-loop processes has met more varied success rates. Certain processes in particular with factors of the type (s-a) (s-ra), r-1 have proved very difficult to stabilise. This paper illustrates how the pre-stabilisation approach to prediction can be used to overcome this bottleneck and with the added bonus of retaining the intuitive tuning parameters that make PFC popular
