集员辨识的次最优输入设计

Near-optimal lnput Design for Set Membership ldentification

讨论了单输入单输出时不变线性系统参数集员辨识的试验设计问题。在输入信号幅度有界的约束条件下 ,分别针对一次完成设计和递推设计给出了确定试验输入信号的公式。这种信号能使辨识得到的椭球所包含的范围在一定意义下较小 ,并且是试验之前的所能做到的最佳选择。

In this paper,the optimal input sequence that minimices the ellipsoid yielded by the set membership identification of a linear time-invariant discrete-time system is discussed.Two formulas are given for online and offline design respectively.
