摘要: 研究自由动态临界稳定仿射系统的输入到状态镇定,通过零状态可探测假设,减弱了 通常的前提条件:自由动态全局渐近稳定;运用无源性原理研究扰动抑制,给出了输出负反馈解 扰动抑制问题的简明条件.分析中用到Legendre-Fenchel变换.Abstract: In this paper, we firstly investigate the input-to-state stabilization of affine systems whose unforced dynamics are critically stable. Using the hypothesis of zerostate detectability we obtain a result that weakens the general precondition that unforced dynamics are globally asymptotically stable. We then apply the passivity theory to studies of disturbance attenuation, and put forward concise conditions guaranteeing negative output feedback to solve disturbance attenuation problems. In our analysis Legendre-Fenchel transformation is used.
