摘要：
The active vibration control of SFSF (Simply Supported-Free- Simply Supported-Free) smart plate by using linear quadratic Gaussian (LQG) controller is described in the paper. In order to design proper optimal control law two pairs of PZT actuators and sensors oriented in two perpendicular directions X and Y are glued to the plate. The aforementioned locations and orientations of PZT elements allow to decouple the TITO system onto two SISO subsystem for separately control odd and even modes. The process of design LQG controller is performed in two stages. In the first stage with using Matlab software the parameters of controllers are determined based on the simulations results in time and frequency domains. On the other hand, in the second step the designed controllers are verified on the lab stand by implemented control laws to real time processor (Dspace).
