临界

It consists of three components: the parameters estimating on-line; the calculating of closed-loop critical gain K and frequency ω; evaluating the PID parameters to enable the closed-loop syetem with the given phase margin.

In this paper, it is pointed out that the accuracy of measurement must be considered for the discussion about the restitution time of damped vibration, and it is in the "critical state of weakly damped vibration" defined by this paper, not the critical damping state, that the restitution time is the shortest.

1 问题的提出和回复时间的定义众所周知，阻尼振动按阻尼的大小可分为弱阻尼、临界阻尼和过阻尼三种情形。几乎所有的教材均指出，临界阻尼运动是物体刚能不做周期性运动而又最快地回到平衡位置的运动，也即其回复时间最短。
