چکیده
|
This paper investigates the possibility and effectiveness of multi-mode vibration control of a plate through real-time fpga (field programmable gate array) implementation. this type of embedded system offers true parallel and high throughput computation abilities. the control object is an aluminum panel, clamped to a perspex box’s upper side. two types of control laws are studied. the first belongs to non-model based control. this control law is designed to generate active damping within the designed bandwidth. the second control law is model based h-infinity robust control. a system identification process is needed before the controller comes out. each of the control laws is implemented on a fpga target, which is powerful enough to achieve high throughput control loop rates. the experimental control results demonstrate that the non-model based control law has sufficient authority to suppress the interesting modes. the model-based robust control law’s control performance is not so positive compared to the previous method. therefore, it is not recommended for this application.
