论文摘要
考虑到非线性不确定系统的控制问题，不确定的控制输入增益的可忍受范围是一个基本问题。本文为基于主动干扰拒绝控制（ADRC）设计的良好表现闭环系统提供了必要的条件。通过提出的必要条件，定量显示了不确定的控制增益的最大可容忍范围，这揭示了ADRC处理与控制输入相关的不确定性的能力。此外，严格分析了基于ADRC的闭环系统的瞬态性能和稳态特性。
Considering the control problem for nonlinear uncertain systems, the tolerable range of uncertain control input gain is a fundamental issue. The paper presents the necessary and sufficient condition for the well-performed closed-loop system based on active disturbance rejection control (ADRC) design. Via the proposed necessary and sufficient condition, the maximum tolerable range of the uncertain control gain is quantitatively presented, which reveals the capability of ADRC to handle the uncertainties related with control input. Moreover, under the proposed necessary and sufficient condition, both the transient performance and the steady state property of the ADRC based closed-loop system are rigorously analyzed.
