【Abstract】 Based on the principle of fuzzy control,a fuzzy control system was illuminated and the basic constitutions of the simplified fuzzy controller for spatial reticulated structures were constructed,which contains fuzzification interface,rules library,interpolation polling list etc.By using this simplified fuzzy controller,the numerical simulation and comparison for vibration control of a typical spatial reticulated structure were carried out,in which the displacement and velocity responses of different nodes were chosen as two input variables.The study indicates that this simplified fuzzy controller is effective in vibration control.更多还原
