论文摘要
在本文中，我们为非线性系统提出了一种新的状态观察者设计技术。它由最近引入的基于参数估计的观察者的扩展组成，该观察者适用于验证特定代数约束的系统。与以前的观察者相反，新的观察者避免了实施可能阻碍其实际应用的开放循环集成。我们给出了这两个观察者的两个版本，一个版本可确保渐近收敛，第二个版本可以在有限的时间内获得收敛。在这两种情况下，所需的激发条件都比经典的激发假设弱弱。结果表明，所提出的技术适用于多支马的动力系统和化学生物反应器的实际重要例子。
In this paper we propose a new state observer design technique for nonlinear systems. It consists of an extension of the recently introduced parameter estimation-based observer, which is applicable for systems verifying a particular algebraic constraint. In contrast to the previous observer, the new one avoids the need of implementing an open loop integration that may stymie its practical application. We give two versions of this observer, one that ensures asymptotic convergence and the second one that achieves convergence in finite time. In both cases, the required excitation conditions are strictly weaker than the classical persistent of excitation assumption. It is shown that the proposed technique is applicable to the practically important examples of multimachine power systems and chemical-biological reactors.
