摘要
En 中文
The fuzzy logic ability to manage nonlinear vibration control problems has one major drawback: the slow reaction time offered by a software-implemented controller. This justifies the adoption of integrated fuzzy chip controllers. Nevertheless, designing a fuzzy controller for structural control purposes requires some fine tuning work. This can be conveniently carried out over an equivalent electronic circuit which emulates a civil structure, rather than by an expensive laboratory environment for testing frame specimens or by using computer simulations which would not allow a real-time study. Conceiving and implementing an electronic circuit equivalent to a single-degree-of-freedom system is the topic of this paper. A case study is finally presented. It discusses the major features of the adopted 'fuzzy chip controller'. A brief overview of the results of the laboratory tests is also given. They were performed in order to properly tune the fuzzy project with civil structure applications.
