Accuracy in the operating range:
To ensure specified accuracy over a normal range of frequencies, the plot may not fall below a given level over this range. To improve accuracy, this level must be raised.
Crossover frequency and bandwidth:
Crossover frequency is a measure of bandwidth , so of speed of response, according to ωc =0.63ωb .
Noise rejection:
To ensure a specified attenuation (reduction) of noise components in the input above certain frequency should be below a certain level.
These criteria show how different aspects of performance are reflected in individual features of the plot and permit specifications to be translated into requirements on the Bode plot. The task of system design
is to derive the compensators that will meet these requirements.

Bode Plot Design
Design of a feedback control system using Bode techniques entails shaping and reshaping the Bode magnitude and phase angle plots until the systems specificatio

准确性,在经营范围:
为确保指定精度超过正常范围的频率,图谋可能不会低于某一特定水平,超过这个范围。以提高准确性,这一水平亟待提高。
交叉频率和带宽:
交叉频率是衡量带宽,所以反应速度,根据
ω c = 0.63 ω
噪音抑制功能:
为确保指定衰减(减少)的噪声成分中输入上述某些频率应低于某一水平。
这些标准如何不同方面的表现,反映在个人特点和阴谋证的规格,以被翻译成要求就预示着阴谋。任务系统设计
是计算应补偿器,将满足这些要求。

波特曲线设计
设计一个反馈控制系统中的应用预示着技术带来的塑造和重塑吉兆幅度和相位角地块,直到系统规格是感到满意的。这些规定是最方便的表达而言,频域数字的优点,如增益和相位裕量为瞬态性能和误差常数为稳定状态的时域响应。和塑造渐近波特图的连续时间系统,由梯级或反馈补偿是一个比较简单的程序。
