Neural Network Modeling and an Extended DMC Algorithm to Control Nonlinear Systems

In this paper we propose a solution to the model predictive control problem for the case when the model is given by a nonlinear neural network. The solution follows the algorithm proposed by Peterson et al.[11] where the linear DMC is extended to handle nonlinear systems by updating the linear model with a `disturbance due to nonlinearities´ term. Simulation results of a reaction in a CSTR are included. Results show the improvement in control of the proposed algorithm over linear DMC.
