Research on pressure stabilized controller of hydraulic shaking table based on rapid prototyping of DSP algorithms using SIMULINK

Theoretically analysis, and an in-depth research was made carried out on the implementation of force decoupling control of hydraulic shaking table. Because controlled DOF is 6 and the platform has 8 exciters, the whole control system is statically indeterminate, and this layout would produce huge endogenetic force during operation, so a pressure stabilized controller is used to reduce the force. 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. Finally, 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.
