It covers both popular dynamic matrix control and generalized predictive control implementations, along with the more general state-space representation of model predictive control and other more specialized types, such as max-plus-linear model predictive

ISA brings you the most authoritative technical resources on process automation, written and reviewed by experts in their fields. You will find books on all facets of automation and control including: process control design, system calibration, monitoring control system performance, on-demand and adaptive tuning, model predictive control, system optimization, batch processing, continuous ?pageid=   CONTROL SYSTEMS Control is used to modify the behavior of a system so it behaves in a specific desirable way over time. For example, we may want the speed of a car on the highway to remain as close as possible to 60 miles per hour in spite of possible hills or adverse wind; or we may want an aircraft to follow a desired altitude, heading,~pantsakl/Publications/A-EEHandbookpdf.
