Abstract
In this paper, we have developed a new ultra high-speed active control system based on the DSP320C6713 microprocessor to control the vibration of the structure actively. The active control system is composed of the DSP320C6713 microprocessor which is the fastest processor in the DSP series, a Piezoelectric(PZT) driver, PZT actuator, and vibration sensor. To compose a compatible system, we composed the A/D and D/A devices with the same speed resolution of the DSP320C6713. Since fast processing is very important in the active control of the vibration, we mainly worked on achieving a very fast loop time. Using the developed system, we have tested the processing time of the processor and peripheral devices for the speed of the loop time, and found that the overall processing time was fast enough to control the vibration mode of the prepared aluminum plate. Also, we have presented two test results with different loop times to identify the superior performance of the DSP320C6713 processor in the fast processing time. We applied the PPF control algorithm to reduce the second mode of the plate, and tested the control system with different loop time. We identified that the active vibration control system shows good vibration reduction performance and that faster loop time shows better result in vibration reduction. In this reason, we have ensured that the proposed control system based on the fast DSP320C6713 would be a prospective control system in active vibration control.
