This paper describes an initial investigation into the use of neural network learning algorithms to obtain a controller for a non-linear system over a large operating space within the context of automotive applications. In order to perform a comparative study of the various adaptive systems, the problem of controlling the motion of a solenoid-operated EGR (Exhaust Gas Recirculation) valve is considered. This study also compares a neurocontroller with a PID controller for various position step changes in both directions. During the investigation it was found that the performance of the neurocontroller was consistently better, particularly for large demanded step changes, and that the neurocontroller consistently used less control energy. Further work will focus on why these nonlinear learning systems outperform perform PID controllers in this application.
