A Study About Fuzzy Control Algorithm Based on Neural Networks Forecast Model in Active Vibration Isolation Control System

The paper designs fuzzy active vibration isolation control algorithm base on neural networks forecast model. It can make forecast for the moving state of vibration isolation platform at the next moment according to output of controller and vibration isolation platform at the current moment. Input this state to fuzzy controller adopts feed-back mode. Fuzzy controller makes diagnosis in advance and controls the vibration isolation platform. The simulation result shows that the algorithm not only limits surge of control signal but also can restrains super high size and has favorable effects for low frequency vibration signal.
