Abstract    This paper investigate 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 synthesis. Each of the control law is implemented on a FPGA target, which is powerful to achieve high throughput control loop rates. The experimental control results demonstrate the non-model based control law has sufficient authority to suppress the interesting modes. The model-based robust control law’s control performance doesn’t has enough highlight compared to the previous method, which is not recommended for this application.

چکیده    در این مقاله امکان و اثربخشی چند حالت کنترل ارتعاش از یک صفحه از طریق زمان واقعی FPGA (درست برنامه ریزی دروازه آرایه) پیاده سازی بررسی میشود. این نوع از سیستمهای جاسازی شده توانایی محاسباتی توان بالا و موازی واقعی را ارائه میدهد. کنترلگر یک پنل آلومینیوم منگنه شده به سمت بالای یک جعبه پلاستیکی از جنس پرسپکس است. دو نوع از قوانین کنترل بررسی شدهاند. قانون اول متعلق به کنترل ناوابسته بر مدل است این قانون کنترل برای تولید میرایی فعال در پهنای باند طراحی شده است. قانون کنترل دوم مدل مبتنی بر کنترل مقاوم H-بی نهایت است. پیش از خروج از کنترل، فرایند شناسایی سیستم مورد نیاز است. هر یک از قوانین کنترل بر روی یک هدف FPGA با توانایی کافی برای دستیابی به نرخ بالای حلقه کنترل، اجرا شده است. نتایج کنترل تجربی نشان میدهد که قانون کنترل ناوابسته بر مدل قدرت کافی برای سرکوب حالت مطلوب را داراست. عملکرد کنترل مبتنی بر مدل قانون کنترل نسبت به روش قبلی چندان مثبت نیست و بنابراین برای این نرم افزار توصیه نمیشود.
