【摘要】 本文利用振型变换技术，将设置了ｍ个控制器的ｎ自由度主动变刚度控制体系降阶为１个自由度的主动变刚度控制体系，进而提出了振型控制律──包括第一振型控制律和主振型控制律。仿真分析结果表明，第一振型控制律可以有效地控制受控结构的相对位移反应，主振型控制律则可以有效地控制受控结构的相对位移反应和层间位移反应。更多还原

【Abstract】 By means of mode orthogonality,two mode control laws for an n-degree-of-freedomstructure with m AVS systems, the first mode control law and the main mode control law, arepresented in the paper. Computing simulations demonstate that both the two control laws, es-pecially the main mode control law, can achieve the evident control effectiveness. The firstmode control law can make the relative displacement responses of the controlled structure beredueed significantly, and the main mode control law can make not only the relativedisplacement responses but also the story displacement responses be reduced effectively.更多还原
