Abstract: Abstract: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 neural network, trained by
Quick-prop with Newton's method, is used to model an approximation
of this fuzzy logic controller, termed the neural
network fuzzy controller (NNFC). The control performance
indicates that the NNFC has the same performance as the FLC
designed in the first phase and its control rule surface is improved
and more suitable for actual use. The results indicate
that the proposed design approach provides a robust, controllable,
practical, and low-cost solution for a FLC of an active
vibration isolation system.
