摘要
针对振动主动控制中的共振及溢出现象 ,提出了采用变结构控制的构想 ;再根据变结构控制的基本理论 ,提出了共振及溢出控制的变结构控制原理、算法 ;并以悬臂梁为模型通过仿真验证了所提出的变结构控制策略对共振及溢出控制的有效性 仿真结果表明 :对于主动振动控制中的共振及溢出现象 ,加速度反馈比阻尼反馈更为有效 ;在对共振及溢出采用变结构控制时 ,控制切换函数或区间的选取对控制效果的优、劣非常重要 。
The paper deals with the resonance and spillover in active vibration control.A variable structure control strategy is put forward. Following the basic theory of variable structure control, a principle and algorithm of variable structure control on resonance and spillove is given and its effectiveness is tested with cantilever by simulation. The results show that acceleration feedback is more effective than damping feedback on resonance and spillover in active vibration control, and switch function or on off band is very important to the controlling effect which has to be discussed further.
