摘要本文主要介绍了日本在土木结构振动主动控制方面的最新发展趋势。首先，对振动控制方法和控制器进行了分类，特别是在机械和土木工程中广泛应用的主动动力吸收器。其次，研究了柔性结构振动控制的基本问题，如设计振动控制器所需的降阶模型的建立、传感器和执行器的正确布置以及如何防止溢出失稳等。最后，对实际应用中的控制理论如线性二次控制理论、H∞控制理论、神经网络理论等课题进行了探讨。
Abstract This paper reports recent trends in active vibration control mainly as developed in Japan for civil structures. Firstly, it classifies vibration control methods and controllers, especially active dynamic absorbers that are widely used in mechanical and civil engineering. Secondly, it addresses basic problems in the control of vibration of flexible structures such as formulating the reduced-order model required for designing vibration controllers, the correct arranging of sensors and actuators, and how to prevent spillover instability. Finally, the practical use of control theories such as linear-quadratic control theory, H∞ control theory, neural network theory and other topics are discussed.
