Dynamic Identification Method of Payload Characteristic Parameters of Active Vibration Isolation Systems
In response to the problem that it is difficult to estimate the load characteristic parameters of the active isola-tion system and its dynamic changes,the identification object of the characteristic parameters was recognized and the identi-fication method was proposed,which improved the decoupling control effect of the active vibration isolation system.The dy-namic model and control model of the active vibration isolation system were established for the vibration reduction system with three-point supported configuration.The mass matrix,stiffness matrix,damping matrix in the dynamic equation and the transformation matrix in the decoupling control model were derived.The identification method of the center of gravity,mass and inertia load characteristic parameters of the active vibration isolation system was proposed,the simulation model of the active vibration isolation system based on Simulink was created,and the experimental platform was built.The effectiveness of the identification method was verified by simulation and experiments.
