|
摘要
提出了结构半主动减震控制的一种新体系———半主动变刚度·阻尼控制系统 ,设计了控制装置 ,推导了控制系统的运动方程 ,提出了基于预测控制的预测瞬时最优控制算法 ,完成了结构模型振动台对比试验 .试验研究表明 ,结构半主动变刚度·阻尼控制系统及其控制算法是十分有效的 ,为该前沿技术的工程应用创造了条件
New system and motion equations of the semi_active variable stiffness·damping control system are suggested. On the basis of predictive control, predictive instantaneous optimal control algorithm is put forward. The comparative shaking table tests of the subject models with and without the AVS·D device were carried out. Results of tests show that the AVS·D system is very effective and confirm that both the control algorithm and software of the AVS·D system are efficacious.
