The next area of research will be focused on the design of a nonlinear predictive controller and nonlinear process identification with a higher order of linear approximation and verification of adaptive NMPC using the Hammerstein-Wiener model and its variations.
In this section, adaptive NMPC practical properties are examined via simulation example.
Since the boiler exhibits considerable nonlinearities as was described in (Horalek & Hlava, 2009), it is not surprising that simulation results will show the higher performance of NMPC in comparison with linear and multiple MPC.
Although the principle of nonlinear MPC (NMPC) is the same as in the linear case, it is well known that design of NMPC is much more complicated mainly due to nonlinear and non-convex optimization that must be solved in every sampling period in very short time (Biegler, 2010).
Examples of challenging problems that may justify NMPC are shown in Figure 1.
In the sections that follow these questions are addressed for several different approaches that (we) have used to handle non-linear systems: (1) Non-linear Model Predictive Control (NMPC) using fundamental models; (2) EKF-based NMPC using successive linearization; (3) Multiple Model Predictive Control (MMPC); and (4) Artificial Neural Network-based MPC.
In the summer of 1996, a telephone survey was conducted using a random sample of households with listed telephone numbers from the NMPC
service territory within Erie County.
In the near future, we believe that the development of both GLC and NMPC
will depend strongly on the development of adequate techniques for nonlinear identification, based on nonlinear empirical models such as artificial neural networks.
schemes have theoretical rigor but have some practical drawbacks.
The next area of research will be focused on the design of a predictive controller with a higher order of linear approximation and verification of NMPC
using the Hammerstein-Wiener model and its variations.

As a certified power marketer, PSEM will be able to expand its scope from brokering excess power from NMPC
to other users, to actively buying and reselling wholesale power from any other power company.
