High-Q micromechanical resonators have been studied intensively because of the tunable performance and the associated potential applications. Nevertheless, some designs experience long relaxation times which hinder fast switching applications. We investigate an open-loop control, an intentional and confined time-periodic variation, that is capable of reducing the transient time allowing rapid switching times. The physical phenomenon is described in detail and analysed using a singular perturbation technique. Analytical conditions are developed for designing future experimentation. The control is proven numerically for an exemplary micromechanical resonator.

通过限制参数激励来增强高Q谐振器的振动衰减

由于可调谐性能和相关的潜在应用,对高Q微机械谐振器进行了深入研究。但是,某些设计会经历较长的松弛时间,从而阻碍了快速切换应用。我们研究了一种开环控制,这是有意限制的时间周期变化,它能够减少瞬态时间,从而实现快速切换时间。详细描述了物理现象,并使用奇异摄动技术对其进行了分析。为设计未来的实验开发了分析条件。对于示例性的微机械谐振器,该控制已在数值上得到证明。
