摘要
Let a discrete-time uncertain system be characterized by a polynomial f(z) = a0z” + a1zn−1 +an, with complex coefficients al = Xi + jyi whose real and imaginary parts belong to some known intervals. The stability of such systems, in the face of coefficient variation, is under question. In this paper, three approaches are presented for robust stability analysis of these kinds of systems. © 1990 IEEE
