| Abstract: | The control law synthesis, wind tunnel test and engineering properties ofdigital active flutter suppression system (AFSS) are presented.A method ofdiscretization of continuous domain is adopted in the control law design, and four kindsof control laws are demonstrated during the wind tunnel test with this method. Thewind tunnel test affirms the correctness of the theoretical computation and the test de-sign. The control law is implemented by use of microcomputer and industry controllerin this test. The engineering properties of the active flutter suppression system are pres-ented. The research on a dynamically scaled wing/ store configuration shows that theflutter speed increases by 20% or so and the performance of the system is basically satis-factory. |
