标题： Generalized Super-Twisting Observer for a class of interconnected nonlinear systems with uncertainties

摘要： 广义超级-twisting观测器（GSTO）被推广用于一类具有有界不确定性的强可观测非线性互联系统的观测问题。文中使用了一个非光滑的强李雅普诺夫函数，在存在不确定性的条件下证明了所提出的观测器对系统真实轨迹的有限时间收敛性。此外，文中通过两个食物生产系统之间的相互作用案例研究，将所提出的观测器与高增益观测器进行了比较。结果强调了GSTO中的不连续项在实现精确估计中的关键作用。 显示英文摘要

摘要： The Generalized Super-Twisting Observer (GSTO) is extended for a strongly observable class of nonlinearly interconnected systems with bounded uncertainties/perturbations. A nonsmooth strong Lyapunov function is used to prove the finite-time convergence of the proposed observer to the true system's trajectories, in the presence of the uncertainties. A case study on the interaction between two food production systems is presented, comparing the proposed observer with the High Gain observer. The results emphasize the critical role of the GSTO's discontinuous term in achieving exact estimation.
