<正>This paper deals with the pole placement of the singular system Ex~.=Ax(t)+Dx(t-(?))+Bu, y=Cx, where x∈R~n,u∈R~m,and y∈R~n are its state,control input and measure output respectively;E,A∈R~(n×n),B∈R~(n×m),and C∈R~((?)×n) are constant matrices.It is also assumed that rankE<n.The results generalize the results of [1].
