Active control of flexural vibrations

摘要: The active control of disturbances propagating along a waveguide is considered with particular reference to the flexural vibrations in thin beams. system consists number point sensors and exciters distributed some manner waveguide. sensor measurements are used as inputs controller which forms required excitations such that incoming completely cancelled. A method by this ideal can be synthesized presented. stability considered. In general reflects downstream cancelled while upstream both reflected transmitted. Active waves beams then two possible systems examined. first displacement rotation at application force moment second comprises points forces. cases derived aspects systems' performances
