- W2384263647 abstract "For the design of active vibration controller,the measurement of the traditional algorithm are velocity and displacement.It brings errors because velocity and displacement is difficult to be measured.So this paper proposed state-derivative feedback equation in which measurement is acceleration based on state space equation.The feedback gain matrix and state-derivative estimator can be determined by Lagrange multiplier method and functional minimization method.State-derivative feedback algorithm of closed-loop control system is formed.According to this algorithm,vibration control of a annular space truss with diameter of one meter is analyzed,and effect of vibration control is evaluated by modal parameter identification of time domain.The control effect on LQR algorithm and state-derivative feedback algorithm is compared by a three layers of shear frame structure.The results show that effectiveness on vibration control is apparent and the algorithm of state-derivative feedback control can apply to active vibration control on spatial structure.And also,state-derivative feedback algorithm is superior over LQR algorithm." @default.
