Abstract

Conventional linear control schemes often fail to provide precise positioning of a control object under the influence of friction, deadzone, saturation, etc. This paper proposes a control scheme for a precise point-to-point positioning system, which behaves well even under the above influences. The proposed scheme is composed of a fuzzy-neural controller. The neural network is employed to improve the performance of the fuzzy logic. To illustrate the effectiveness of this scheme, experiments are carried out for the cases of a fuzzy controller, the proposed fuzzy-neural controller, and the results are compared with each other.
