本研究提出了一种抑制结构系统响应的主动控制方法。本控制方法是线性二次高斯（LQG）和输入估计方法的综合算法。通过使用综合方法，由于适当的控制力的作用，可以更有效地抑制结构振动。本文对集总质量系统的主动振动控制进行了数值模拟，以验证所提算法的可行性和有效性。仿真结果表明，该方法对于具有外部激励力的结构的控制性能优于传统的LQG方法。
This study proposes an active control method to suppress the responses of structural systems. The present control method is a synthesis algorithm of the linear quadratic Gaussian (LQG) and input estimation approaches. By using the synthesis method, structural vibrations can be suppressed more effectively due to the actions of the proper control forces. In this work, numerical simulations of active vibration control of lumped-mass systems are performed to verify the feasibility and effectiveness of the proposed algorithm. The simulation results demonstrate that the control performance of the present method for structures with external excitation forces is better than that of the conventional LQG approach.
