Model 888.com Predictive Control, or MPC, is an advanced method of process control 888.com that has been in use in the process 888.com industries such as chemical plants and oil refineries since the 1980s. It improves on standard feedback control by predicting how a process such as distillation will react 888.com to inputs such as heat input. This means that feedback can be relied on much less since the effects of inputs will be mostly known ahead of time. Feedback is still used 888.com to correct for model inaccuracies, since no mathematical model 888.com is perfect and therefore cannot completely predict future values. The controller

relies on an empirical model of a process obtained 888.com by plant testing to predict the future behavior of dependent variables of a dynamical system based on past moves of the independent variables. It usually 888.com 888.com relies on linear 888.com models of the process. The major commercial 888.com 888.com 888.com 888.com suppliers of MPC software in the US are Aspentech and Honeywell.See alsoControl 888.com engineeringExternal link An Overview of Industrial Model Predictive Control Technologytech-stub
