Using Evolutionary Computation to Facilitate Development of Neurocontrol

The field of neurocontrol, in which neural networks are used for control of complex systems, has many potential applications. One of the biggest hurdles to developing neurocontrollers is the difficulty in establishing good training data for the neural network. We propose a hybrid approach to the development of neurocontrollers that employs both evolutionary computation (EC) and neural networks (NN). The survivors of this evolutionary process are used to construct a training set for the NN. The NN learns the training set, is able to generalize to new system states, and is then used for neurocontrol. Thus the EC/NN approach combines the broad, parallel search of EC with the rapid execution and generalization of NN to produce a viable solution to the control problem. This paper presents the EC/NN hybrid and demonstrates its utility in developing a neurocontroller for the pole balancing problem.
