In this paper, the finite-time state estimation problem is studied for nonlinear systems. For reducing the waste of resources which is caused by data transmission, an event-triggered mechanism is adopted to release the measurement output of nonlinear systems to the estimator when the triggered function is satisfied. The error system is obtained by estimating the state of nonlinear systems. We obtain the finite-time bounded criterion of the error system according to the Lyapunov stability theory and the finite-time bounded theory. At last, the effectiveness of the proposed results is proved by two examples.

基于事件触发机制的非线性系统有限时间状态估计

本文研究了非线性系统的有限时间状态估计问题。为了减少数据传输造成的资源浪费，采用事件触发机制，在满足触发函数时，将非线性系统的测量输出释放给估计器。误差系统是通过估计非线性系统的状态获得的。根据李雅普诺夫稳定性理论和有限时间有界理论，我们得到了误差系统的有限时间有界判据。最后，通过两个算例证明了所提出结果的有效性。
