摘要
本文提出了振动控制系统的四项性能指标,为系统分析与设计提供了理论依据,它也是系统优化设计和评定的准则。本文提出的位移速度控制律发展了传统的位移控制律,为系统控制提供了两个可调参数。控制中同时改变系统的等价阻尼比和控制增益,可以很好地协调各性能指标,在保证系统稳定性的前提下,提高系统的控制效果。
The 4 performance indices of the vibration control systems are proposed in this pa per, which has furnished the theoretical basis for the system analysis and design. The coordinate relationship of each performance index will be considered during the control system design, so as to ensure the systcm maintain higher stability and better control quality. Consequently, these 4 performance indices are the criteria for the system optimum design. The displacement-velocity system control law proposed in this paper also has developed the traditional displacement control law, which provides two regulated parameters for the system control. The equivalent damping ratio and the control gain are changed coordinatedly in control. Each performance index of the system will be well regulated and the effect of the system control will be promoted with the premise of the system stability ensured.
