已识别模型的精度取决于输入信号的选择。激励的持续性是这类信号的必要判据。在本文中,我们开发了输入信号选择的附加准则,特别是,每个时间步长的输入选择都是为了最小化下一个时间步长的系统估计的预测方差。我们将该方法推广到有限视界输入选择问题,并在仿真中进行了验证。
The accuracy of an identified model depends on the choice of input signal. Persistency of excitation is a necessary criterion for such signals. In this paper we develop additional criteria for input signal selection, in particular, the input at each time step is chosen to minimize the predicted variance of the system estimate at the next time step. We extend the method to the finite-horizon input selection problem and demonstrate the method in simulation.
