摘要：
This paper is concerned with the stability of zeros of the discrete-time multivariable system composed of a generalized sample hold function (GSHF), a continuous-time plant with the degrees of infinite elementary divisors being two or three, i.e., mu(1) = ... = mu(m-k) = 2 and mu(m-k+1) = ... = mu(m) = 3 (k = 1,..., m, 0 <= k <= m - 1), and a sampler in cascade. The properties of the limiting zeros are studied and conditions for ensuring the stable limiting zeros of the discrete-time systems for sufficiently small sampling periods are derived. It is a natural extension of Liang et al.'s result for single-input-single-output systems to multivariable systems.
