Predictive control is a powerful tool in dealing with those processes with large time delays. Generalized Predictive Control (GPC) is the most popular approach to the subject, and this text discusses the application of GPC starting with the concept of long-range predictive control and its need in medicine (particularly automated drug deliveries). The concept of adaptation is also emphasized with respect to patient-to-patient parameter variations. Subsequent chapters discuss interactions, comparisons and various aspects of GPC. The book concludes by putting into perpective the generic nature of the architecture built around GPC and which provides model-based fault diagnosis with control.
