Closed loop circuit 闭环电路
Based on the fault tree analysis ( fta ) , the main loop circuit of electrical life - test device is studied and its corresponding fault tree constructed 在故障树分析理论的基础上,对电寿命试验设备的主回路进行了分析,并建立相应的故障树。
The method is to judge whether a system is stable by analyzing the amplification of loop circuit based on amplitude frequency response and phase frequency or not 这种方法是将电路的幅频特性和相频特性曲线结合起来对环路增益进行分析,以此作为判断系统是否稳定的依据。
This paper suggests that there is another better way to judge whether a system is stable or not - that is analyzing the amplification of loop circuit with the nyquist rule 由于激励信号是复数形式的变化量,因此我们还可以采用奈奎斯特准则,利用奈奎斯特图在复平面上的变化特点,对环路增益进行分析。
