If the initial condition is zero in a first - order circuit , the response to it is called the zero - state response 如果電路的初始狀態(tài)為零,那么電路的響應(yīng)稱為零狀態(tài)響應(yīng)。
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 借助零狀態(tài)可探測概念,減弱了通常文獻中所需的前提條件,在此基礎(chǔ)上研究了一類輸入飽和線性系統(tǒng)的輸入到狀態(tài)鎮(zhèn)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 運用仿射無源系統(tǒng)的kalman - yacubovitch - popov引理,飽和鎮(zhèn)定非仿射非線性系統(tǒng);運用聯(lián)級無源系統(tǒng)的穩(wěn)定原理魯棒鎮(zhèn)定幾類不確定系統(tǒng);運用零狀態(tài)可探測概念,給出了鎮(zhèn)定從驅(qū)動系統(tǒng)相對較弱的充分條件。
