Clarke, D.W., C.Mohtadi and P.S. Tuffs (1987). Generalized Predictive Control- Part 1: The basic algorithm. Automatica, 23, 137-148 Controlled Auto-Regressive Integrated Moving Average (CARIMA) 3-A CARIMA model is used to obtain good output predictions and optimize a sequence of future control signals to minimize a multistage cost function defined over a prediction horizon. The inclusion of disturbance is necessary to deduce the correct controller structure. 2- It also tracks both varying and constant future set points. 1- Most of the time noise shows drifting characteristics and also offset free response.

Multi-Step Ahead Prediction for a CARIMA model (cont.) Multi-Step Ahead Prediction for a CARIMA model (cont.) Step 1.
Define the vector formulation of the cost function:
Step 2.
Substitute y Step 3. State the required minimisation after expanding contains terms that do not depend upon
and hence can be ignored Step 4. Step 5.
The GPC control law is defined by the first element of Summary: The computation is recalculated at each sampling instant and therefore the control law is: Transfer function representation of the control law The control law: Predictive control with a state-space model The predictions for state space model Predictive control with a state-space model Computing the predictive control law Step 1. Find prediction equations Step 2.
