摘要：The paper investigates the stability of zero dynamics of the exact sampled data systems composed of a backward triangle sampled and hold (BTSH), a continuous-time multivariable plant and a sampler in cascade. Then a new zero dynamics polynomials is established and it can reflect the relationship of zeros between general linear continuous time systems and the exact sampled data systems. The properties of the limiting zeros are studied and the stability conditions of limiting zeros of exact sampled data systems for sufficiently small sampling periods are derived. We show that the zero dynamics of the discrete time systems can be stabilized by selecting proper parameters of the BTSH. Simulation results are provided to show the good performance and stabilization of the corresponding zero dynamics.
