给出了具有快速时变不确定系数的线性控制系统的例子，这些系统可以用非线性无记忆状态反馈镇定，但不能用线性时不变动态状态反馈镇定。通过其中一个例子，我们表明，闭环二次稳定裕度可能比实际的稳定裕度无穷小。
Examples of linear control systems with fast time-varying uncertain coefficients arc given, which can be stabilized by a nonlinear memoryless state feedback, but cannot be stabilized by a linear time invariant dynamic state feedback. By means of one of these examples we show that the closed-loop quadratic stability margin may be infinitely smaller than the actual stability margin.
