Efficient Hammerstein Wiener model can be determined by considering fitness of the model, loss function value and final prediction error. Using these data the model which best fits the process can be determined. A model based controller that uses Hammerstein Wiener model as the internal model for a nonlinear MPC as Hammerstein based Model Predictive Controller (HMPC) is used in controlling pH neutralization process. The simulation results show that Hammerstein based Model Predictive Controller (HMPC) outperforms linear Model Predictive Controller (MPC) for control of pH process.
