Abstract :
The experimental results of using trained neural networks to regulate the pitch attitude of an underwater telerobot are presented. The neuromorphic control algorithm developed for teaching the networks is a direct application of the back-propagation entrainment method, with those modifications required to pose the problem in a control systems framework. The networks perform in the field as predicted by simulation results; however, it is observed that the complexity of the calculations required can create unacceptable delays when using a single serial microprocessor to compute the control. This problem becomes especially acute when scaling the architecture to more complex neural topologies. Special-purpose hardware, which directly implements the neural equations and, hence, realizes the benefits of the natural parallelism of these models, is seen as a necessary development for the effective use of neural controllers.<>
