Linear, Polynomial, and Look-Up Table Models
This chapter analyzes some classical or traditional model architectures for nonlinear static processes. These model architectures are widely used in theory and practice. The simplest approach pursued in Sect. 10.1 is to approximate the nonlinear process behavior with a linear model. In the subsequent section, the polynomial approximator is discussed. Finally, in Sect. 10.3 the standard grid-based look-up table with linear interpolation is analyzed.
