SISO系统参数辨识的局部最优信号

Locally Optimal Signal for Parameter Identification of SISO System

讨论了线性离散时间ＳＩＳＯ系统的参数辨识的最优信号问题，在Ｄ—最优准则下导出了一个离线辨识的局部最优信号算法，并且根据该算法为某水轮机组系统参数辨识，设计出一局部最优试验信号．

This paper investigntes how to generate optimal input Signal series for the identifhcation of linear discrete - time systems. An algorithm of the locally optimal input signal is given according to D-optimal critcria and a locally optimal input signal for dynamic system parameter identification is designed using this algorithm.
