本文提出了一种考虑作动器约束的主动动力吸振器结构振动控制设计方法。利用双曲正切非线性函数，建立了同时考虑最大控制输入和作动器最大行程的线性变参数系统。基于线性矩阵不等式的增益调度控制，使得闭环系统稳定，即使执行器出现饱和现象，也具有良好的性能。通过仿真，我们验证了所提出的方法是有用的，不仅是一个脉冲输入，但也非平稳随机输入，如地震。
This paper proposes a design method for vibration control of a structure with an active dynamic vibration absorber involving actuator constraints. We formulate the linear parameter varying system taking into account both the maximum control input and the maximum stroke of the actuator by using a nonlinear function of hyperbolic tangent. The gain-scheduled control based on the linear matrix inequality is obtained so that the closed-loop system is stable and has good performance even if saturation phenomena of the actuator occur. By simulations we verify that the proposed method is useful for not only an impulsive input but also a non-stationary random input such as earthquakes.
