Predictive Control : Process Modeling

The efficiency of an identification method will depend entirely on the nature of the isodistance domains (figure 17). If the isodistance domain is spherical (figure 17), the direction of the local minimum OL (gradient at a given point) is also the direction of the global optimum OG (minimum criterion point). All methods, and in particular the most elementary gradient method, converge within a few iterations. In the case where the isodistance domain has an elongated "banana" shape (figure 17), the directions of the local optimum OL (gradient)...
