| 摘 要： | 以框架结构为研究对象,在设计出作动器的前提下,对结构设计参数进行摄动,以控制效果为优化目标来确定最优设计参数。在模型降阶方面,选择了基于系统内平衡理论的降阶方法。考虑到磁流变阻尼器的非线性特点及结构设计参数发生摄动时系统的可控性,研究了控制力为阶跃函数和具有较大的增益裕度的广义预测控制,并提出了相应的半主动控制方法,最后给出了计算实例。

| Abstract: | The frame structures are taken as study object, under the premise of designed actuators, the optimal design parameters can be acquired by taking control effect as optimization aim and by aid of the structural parameters perturbation.Acondensing method based on an internal balancing theory is proposed in the paper. Considering the non-linearity of magnetorheological damper and system controllability of changed structural parameters, a generalized predictive control scheme which has bigger plus area and adopts step function as control force is introduced.Finally a numerical example is presented. |
