【Abstract】 Taking advantage of the real-time measuring controlling system, the smart structural vibration signal can be sampled, filtered, analyzed and the smart structural vibration will also get to be controlled and suppressed in real-time. This paper introduces the hardware structure and software design of a host and slave type of vibration active control real-time measuring-controlling system composed of TMS320 VC33 digital signal processor and personal computer. The real-time measuring and control software can be used to model the system, to identify system parameters to control law simulation and to optimize sensor and actuator place is correct valid and stable.更多还原
