三、前向网络方法以上讨论的是闭环方法 ,但是无论是直接反馈法还是间接反馈法 ,其反馈信号都会对系统的稳定性带来一定的影响。因为反馈支路在时间上总是存在着延迟 ,因此在频率很高的情况下相移会很大 ,导致系统不稳定。于是许多人把目光转向了前向网络线性化方法。前向网络 Third, the forward network method The above discussion is a closed-loop method, but whether it is direct feedback method or indirect feedback method, the feedback signal will have a certain impact on the stability of the system. Because the feedback branch always has a delay in time, the phase shift can be large at high frequencies, resulting in system instability. So many people turned their attention to the forward linearization method. Forward network
