Abstract
Multi-exciter vibration test control system is the core of the multiple shaker vibration test, and multi-exciter vibration test control technology has become the hot point of vibration test field. Based on coherence principles, the coherence of two exciters control system was tested, the introduction of noise signal reduces the control coherence between the response spectrum and partial coherence between response and the corresponding drive signal. By means of increasing the coherence between drive signals, the control coherence between the response spectrum can be raised and control performance of system can be Improved. The above means could provide technical support for multi-exciter vibration test system development.
