Approaching the filter circuit from the frequency perspective will force you to consider issues such as the filter bandwidth design and order (number of poles).
从频率的角度设计滤波器电路,必须考虑诸如滤波器带宽设计和阶数(极点的数量)之类的问题。
The classification and features of ATSE is introduced. Problems such as ATSE transfer time, the usage categories, the choice of the number of poles, etc. in the actual project are expounded.
摘 要 介绍了ATSE 的分类及其特点,并对实际工程中 ATSE 的转换时间、使用类别、极数的选择等问题进行了阐述。
在电气工程与控制系统领域,"number of poles"(极数)是一个核心概念,具体含义需结合应用场景理解:
指电机定子或转子绕组形成的磁场极性对数。每对磁极包含一个N极和一个S极。例如:
公式:同步转速 $n_s = frac{120f}{P}$ (f为频率,P为极数)
此定义直接影响设备转速-转矩特性,风电发电机常采用多极设计适应低速风能
指系统传递函数分母多项式方程的根(Roots),反映系统动态特性:
示例:传递函数 $G(s) = frac{1}{(s+2)(s+3s+5)}$ 的极数为3
航空航天控制器设计需精确分析极点分布
核电站保护系统需验证极点配置可靠性

“Number of poles”是一个技术术语,其含义需根据上下文具体分析,主要涉及以下两种常见解释:
根据使用场景选择合适解释,避免混淆技术术语与日常用语中的“poles”。
