Soft Computing Technologies In Design Of Fuzzy Controller For Active Vibration Isolation Systems, Inn-Tong Chiu, Chih-Chung Fang

Journal of Marine Science and Technology

In the paper, we develop a two-phase design approach for a fuzzy logic controller (FLC) of an active vibration isolation system, which adopts two components of soft computing techniques, namely fuzzy logic control theory and neural networks. First, we design a fuzzy logic controller for an active vibration isolation system using fuzzy logic control theory. We conduct numerical simulations of an active vibration isolation system with three kinds of exciting loads. The results indicate that the performance of the fuzzy logic controller is very good, but its control rule surface does not measure up in practical terms. Secondly in the …
