If the initial condition is zero in a first - order circuit , the response to it is called the zero - state response 如果电路的初始状态为零,那么电路的响应称为零状态响应。
The usual precondition guaranteeing input - to - state stabilization by exploiting the concept of zero - state - detectability is weakened , and a class of linear systems subject to saturation by using the results above is input - to - state stabilized 借助零状态可探测概念,减弱了通常文献中所需的前提条件,在此基础上研究了一类输入饱和线性系统的输入到状态镇定。
Non - affine nonlinear systems via bounded controls and kalman - yakubovitch - popov lemma of affine passive systems are stabilized . several kinds of nonlinear systems with uncertainty by using stability theory of cascaded passive systems are stabilized robustly . the relative weaker sufficient conditions of stabilizing a class of driven - driving systems by using the concept of zero - state - detectability are put forward 运用仿射无源系统的kalman - yacubovitch - popov引理,饱和镇定非仿射非线性系统;运用联级无源系统的稳定原理鲁棒镇定几类不确定系统;运用零状态可探测概念,给出了镇定从驱动系统相对较弱的充分条件。
