Abstract

Vibration control of resonant system is an important problem in industry applications. The reason is that degradation of task accuracy and destruction of materials are caused by vibration. Under such a background, state feedback control, H∞ control, and resonant ratio control based on lumped parameter system have been researched for vibration suppression of system with flexible mechanism. On the other hand, methods in distributed parameter model need a lot of calculation in time domain design. In this paper, to suppress vibration of resonant system, a novel position controller based on a transfer function of wave equation is proposed. Superposition of a traveling wave and the reflection wave causes ordinary wave and vibration occurs. Therefore, a method of reflected wave rejection is proposed. Moreover, the proposed method is applied to a two-mass resonant system and three-mass resonant system. Because the proposed method is based on a distributed parameter model, all vibration modes can be suppressed. The effectiveness of the proposed method is verified by experimental results in a 2-mass and 3-mass resonant system.

用波动补偿器抑制谐振系统的振动

谐振系统的振动控制是工业应用中的一个重要问题。其原因是振动引起任务精度的降低和材料的破坏。在此背景下，研究了基于集总参数系统的状态反馈控制、H∞控制和谐振比控制等柔性机构系统的振动抑制方法。另一方面，分布参数模型中的方法在时域设计中需要进行大量的计算。为了抑制谐振系统的振动，提出了一种基于波动方程传递函数的位置控制器。行波与反射波叠加产生普通波并产生振动。为此，提出了一种抑制反射波的方法。并将该方法应用于双质量谐振系统和三质量谐振系统。由于该方法基于分布参数模型，因此可以抑制所有振动模式。在2质量和3质量共振系统中的实验结果验证了该方法的有效性。
