Vibration control system with function of null adaptive tracking

The invention discloses a vibration control system with a function of null adaptive tracking, and the system comprises a vibrating table driver; a vibrating table; and a displacement sensor. The output end of the vibrating table driver is connected with the control end of the vibrating table. The displacement sensor is disposed on the vibrating table, and the signal output end of the displacement sensor is connected with the vibrating table driver. Compared with the prior art, the system solves a problem of null offset in a mode of electrical automatic control, can automatically adjust the null point of the vibrating table, and achieves automatic matching of different test parts. Compared with a mode of manual adjustment, the mode employed by the system is simple in operation, is flexible in use, and is stable and reliable. Meanwhile, the system can automatically track and adjust the null point of a vibration system, thereby improving the accuracy and performance of dynamic response of a vibration testing system.
