Vertaling van "loop gain" in Chinees

回路增益

环路增益

环增益

Higher stability can be obtained with higher servo loop gain.

用较高的伺服回路增益可以获得较高的稳定性。

as the closing velocity, which is found in the loop gain above, varies greatly with the geometry of the intercept, altitude, target type etc, it is desirable to include the closing velocity in the guidance law

同时考虑到，在上面的回路增益因子中出现的接近速度，是一个会随着拦截过程的相对几何位置、飞行高度、目标类型等参数的不同而发生很大变化的参数，因此，把这个接近速度参数包含到制导法则里，是个相当合理的做法

Both of these metrics can directly impact an important stability criterion for a control loop: unity-gain phase margin- the difference between the actual phase angle of the loop response and -180º at a loop gain of 1.

这两个指标可以直接影响控制环路的一个重要稳定准则：单位增益、相位裕量 -环路响应的实际相位角度和-180º之间的差值，环路增益为1。

So long as the loop gain (i.e., the product of open-loop and feedback gains) is very large, the circuit gain will be determined entirely by the amount of negative feedback (i.e., it will be independent of open-loop gain).

只要环路增益（即开环增益和反馈增益的乘积）是非常大的，电路增益将完全由负反馈量决定（将与开环增益无关）。

Since the same servo loop gain can be achieved for both the recording and the reproduction, it is allowed to perform servo control such as for tracking or focusing control always in a suitable manner.

（2）由于伺服环增益的控制在记录和重放时都能取得，所以可以以适当的方式实现伺服控制如跟踪或聚焦控制。

Reduce the position loop gain

降低位置环增益

The low-frequency component changes toward the target value of the spot position servo according to a speed determined by the loop gain of the spot position servo (time period 403), and stabilizes when the target position for the spot position servo is reached (time period 404).

低频成分按照光点位置伺服的环路增益决定的速度向着光点位置伺服的目标值变化（期间403），在到达光点位置伺服的目标位置时稳定下来（期间404）。

compensating the error to produce a compensated output value by increasing low frequency loop gain and maintaining reduced sensitivity to variations in the response to torque inputs of the traction wheel to generate said clutch engagement signal to thereby engage the friction clutch in a manner causing said transmission input speed signal to asymptotically approach said engine speed signal.

通过增加低频环路增益并通过维持对驱动轮的力矩输入所引起的变化的、已降低了的灵敏度来补偿所述误差，以产生经过补偿的输出值，从而产生上述的离合器啮合信号以便使摩擦离合器按照使上述的传动系统输入速度信号以渐近方式接近上述的发动机速度的方式进行啮合。

Once an HLLB measurement run is completed on a fiber pair, the difference in loop gain between adjacent repeaters is calculated, and then compared to earlier measurements to detect system changes.

一旦在每对光纤上完成了高损耗回路路径测量运行，就可以计算出相邻中继器之间的环路增益差，然后再与之前的测量值相比较，检测出系统变化。

The focus servo circuit 32 performs servo computation (performs phase compensation and adds loop gain) on the focus error signal FE to produce a focus servo signal FS.

First, the tracking error signal TES that is output from the LPF 22 illustrated in FIG. 3 described above is input to a T servo filter 30 (T is an abbreviation of tracking) that is provided in the servo circuit 7. The T servo filter 30 executes filtering for the above-described phase compensation or the loop gain processing and generates a tracking servo signal TS. As illustrated in FIG. 6, the tracking servo signal is input to a switch SW.
