Abstract:
Taking the building structures with base-isolation as study object, the vibration active control of friction pendulum isolation bearings is investigated. On purposes of control algorithm design, the nonlinearities of the isolation system of vibration equations are treated as a form of outer excitation. To solve the state equations and control force, this paper presents a practical double-state-equations method. Meanwhile, a linear quadratic Gaussian(LQG)control strategy with inter-story output responses is provided to reduce the responses of isolation system. In addition, a relative stability matrix is introduced to meliorate the stability of control system. The Kalman filter is in the form defined by the third benchmark buildings. Finally, the simulation analysis and experimental comparison are given.
