论文摘要
在此简短说明中,我们提出了两个新的参数标识符,其估计值在弱的间隔激发假设下会在有限的时间内收敛。主要新颖性是,与其他有限连接时间(FCT)估计器相比,当参数变化时,我们的方案保留了FCT特性。我们的FCT估计器的先前版本只能渐近地跟踪参数变化。提出了新估计器的连续时间和离散时间版本
In this brief note we present two new parameter identifiers whose estimates converge in finite time under weak interval excitation assumptions. The main novelty is that, in contrast with other finite-convergence time (FCT) estimators, our schemes preserve the FCT property when the parameters change. The previous versions of our FCT estimators can track the parameter variations only asymptotically. Continuous-time and discrete-time versions of the new estimators are presented
