Research on three-axis six-DOF shaking table based on rapid prototyping of DSP algorithms using SIMULINK

Three axes hydraulic shaking system as the means to recreate vibration environment can accurately reproduce reference power spectrum density and time history response. The vibration control is a key technique to meet the requirement. This paper introduces the principle of the three-axis six-DOF shaking table at first and then designs hardware system using TMS320C2812 to acquire the analog and digital variable and using TMS320C6713 to operate and communicate with S3C2410 via dual-RAM in order to improve real-time and rapidity of the system. 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 of executable code to the Texas Instruments’ TMS320C2812 and TMS320C6713.
