Abstract: his paper presents the control law design, experience and its relative properties in digital active flutter suppression system. A method of discretization of continuous domain is adopted in this control law design,and we have obtained their digital control law with this method to four sorts of control law. The wind tunnel test affirms the correctness of the theoreti-cal calculation and the test design. The control law is implemented by use of microcomputer and industrial controller in this test.The properties of the active flutter suppression system are raised according to engineering application. The research to a dynamically scaled Wing/Store configura-tion shows that the flutter speed has increased by 20% or so and the performance of this system is basically satisfactory.

Key words: flutter-retarding, control theory, wind tunnel tests
