论文摘要
鲁棒性保证是在控制设计期间要寻找的重要属性。它们可以确保面对不确定性，未建模的效果和有界干扰的闭环系统的稳定性。尽管在连续的非线性框架中已经很好地确定了关于稳健稳定性的理论，但对于其离散时间对应而言，这一理论不能说明。在本文中，我们提出了连续时间非线性系统的总稳定性结果的离散时间平行。这可以通过离散时间上下文中的简单模型差异来分析鲁棒性属性。首先，我们研究名义模型的存在如何转移到足够相似的模型。然后，我们在
Robustness guarantees are important properties to be looked for during control design. They ensure stability of closed-loop systems in face of uncertainties, unmodeled effects and bounded disturbances. While the theory on robust stability is well established in the continuous-time nonlinear framework, the same cannot be stated for its discrete-time counterpart. In this paper, we propose the discrete-time parallel of total stability results for continuous-time nonlinear system. This enables the analysis of robustness properties via simple model difference in the discrete-time context. First, we study how existence of equilibria for a nominal model transfers to sufficiently similar ones. Then, we provide results on the
