Active Vibration Control of a Three-Dimensional Flexible Frame Structure : Spillover Completely Eliminated Response Analysis

Search this article

Description

A modal analysis is presented for predicting the response of a frame structure controlled by a small number of sensors and actuators with high accuracy, with short computation time, and without causing any observation or control spillover. The time response is determined by solving integral equations with respect to only the member joint displacements. The integral equations can be solved by transforming them into ordinary differential equations and by introducing additional mass corresponding to the inertial force due to the rigid-body axial translation and rotation of memhers. Detailed explanation is given on the complete elimination of the spillover by the present analysis. Numerical examples deal with the control of the position, attitude and elastic deformation of a space structure and a manipulator arm, a vehicle frame supported by nonlinear springs and a frame with a dynamic absorber used for economizing the energy consumed for the active control.
