Secondly, a conjecture about the stability for these systems is proposed based on the sufficient and necessary condition of the isolated transfer function being positive real. When the zeros and poles of the transfer functions lie in the imaginary axis, a known conclusion is derived from the conjecture; while the zeros and poles are on the real axis, a new result is obtained and is proved in this note. Finally, according to the conjecture, an example with poles existing on the complex plane is presented, which is not only interesting but also challenging.

然后， 基于所有孤立部分传递函数都正实的充分必要条件给出了上述系统为稳定的一个猜想，当传递函数的零极点都位于虚轴上时，由这一猜想得到了一个已知的结论；当传递函数的零极点都位于实轴上时，由这一猜想得到了一个新的结论，本文证明该结论是正确的；最后，根据这一猜想，给出了传递函数极点位于复平面的一个例子，它涉及到一类系数矩阵为时变正定矩阵的振动方程的稳定性问题，值得去深入研究。

According to analysis of roots locus,fast excitation tends to decrease damping of power systems which is controlled by AVR than slow excitation.But eigenvalues of power system are far from imaginary axis and strong damping is obtained when fast excitation system is added.

在高放大倍数的AVR控制下，快速励磁较慢速励磁更容易恶化系统阻尼；但是在同时附加励磁控制的情况下，快速励磁可使系统的机电模式根轨迹远离虚轴，机电模式阻尼较大；而慢速励磁下，系统机电模式根轨迹接近虚轴，机电模式阻尼较小，快速励磁优于慢速励磁。

It is proved by the analytical and numerical method that the modulus of the Z transform of a finite impulse response sequence has no extreme values at poles (with maximums along imaginary axis and no extreme values along real axis), and the negative second order derivative of the modulus normalized along frequency axis with respect to angular frequency has maximums at the poles.

This paper gives the time domain integral constraints of the feedback control systems tracking error that arise from the presence of stable zeros on or near the jω-axis, which shows that for a linear time invariant system, in order to guarantee the stability of the closed-loop system, the time domain integral constraints must be satisfied by the tracking error.
