摘　　要：采用正弦振动幅值控制技术和相位同步控制技术,设计出多振动台正弦振动同步控制算法。利用Matlab Simulink平台进行仿真,仿真结果表明:采用DFT谱分析四象限反正切方法能准确得到两个正弦信号之间的相位差;所设计的算法能实现多振动台在正弦振动中频率、幅值和相位的同步。提出了在多振动台正弦振动同步控制中需要注意的几个细节问题。This paper designed a synchronous sine vibration control algorithm of multiple shakers by using amplitude control technology and phase synchronization control technology. With Matlab Simulink, the results of simulation showed： the phase difference between sinusoidal signals can be obtained with DFT four quadrant arctangent; the frequency, amplitude and phase synchronization in sine vibration of multiple shakers can be achieved with the algorithm. In the last, several problems in synchronous sine were presented.
