Abstract: In this paper，DSP TMS320F2812, as the core device, acquires structural vibration response data by itself A/D peripheral, and provides output control signals for active vibration through the multi-channels D/A converter DAC7724, which interfaced with the complex programmable logic device EPM7128SQC100.The smart structure active vibration control system have satisfied the request of MIMO (Multiple Inputs Multiple Output) and distributed control. And the whole system’s hardware and software design and implementation is given.
