Abstract： More and more people have attached greater importance to the multi-exciter vibration testing system since it can be able to simulate the vibration environment more real, and now it has become a development tendency of environmental vibration test. The basic control principle of multi-exciter vibration testing system，and key technologies of time-domain waveform replication , which includes iterative algorithm and overlap connective of driving signal, and frequency spectrum replication, which includes feedback correcting algorithm and time randomization are introduced in this paper. At last, this paper gives a summary and prospect of control technology for multi-exciter vibration testing.
