On the basis of theory analysis, deep research was made about the implementation of force decoupling control of hydraulic shaking table. Because tested specimen has eccentric and height, which produce flywheel moment and overturning moment, and causes the non-synchronization of every exciter, so transient force decouple control (TFDC) strategy is introduced in order to remove this effect. Then, the control strategy was realized based on DSP rapid prototyping. TMS320C2812 DSP was applied to acquire the analogue and digital; TMS320C6713 DSP was used to operate and communicate with embedded processor S3C2410 by dual-RAM in order to improve real-time and rapidity. In the end, this paper presents the implementation of a rapid prototyping control system, which involves the design of DSP algorithms using MATLAB Simulink blocksets, automated code generation in the CCS integrated development environment, and downloading the executable code to the Texas Instruments TMS320C2812 and TMS320C6713.
