چکیده
In this paper, the phenomenon of pressure servo valve system self-excited oscillation is studied, dynamic model established, and validity verified by experimental analysis. On basis, it concluded that with constant amplitude nondecaying caused oscillation. Such a comes from unreasonable structure design valve. Moreover, factors affecting are evaluated qualitatively. order to suppress oscillation, paper proposes optimization method based on weakening positive feedback effect backpressure. The simulation results show can effectively eliminate stability margin analysis shows after optimization, has adequate margin.

Identification of the Pneumatic Servo System Using the Self-excited Oscillations
The paper describes the identification of the variable critical gain and natural frequency of the pneumatic cylinder using the self-excited oscillations method. The pneumatic drives are characterized by the low stiffness of the pneumatic cylinder which depends on the piston position and determines the natural frequency of the cylinder. The variety of the stiffness in dependence on the piston po...
