Research on servo-controller for three-axis six-DOF shaking table based on DSP

摘要：

In this paper, a scheme for digital servo-controller of three-axis six-DOF shaking table based on DSP is put forward after analyzing the principle of the servo-valve of the shaking table. TMS320C28335 is used as the processor for data processing unit to carry out the control variables. TMS320C2812 expanded with AD7665 and AD7846, is adopted to acquire analog and digital signals, and is also used as the generator of the driving signal for the servo-valve. CY7C025(one dual-port static RAM) is adopted to accomplish the communication between the data processing unit and the data acquisition system. Simulated and test results of key control units show that the servo-controller can overcome bad consistency of hydraulic cylinder and meet the requirement of design.
