## This paper considers the problem of optimally approximating high-order transfer functions by low-order ones with a time delay. The performance index used for optimization is the integral of squared error (BE) between the unit-step responses of the reduced-order and original transfer functions.

In this paper, practical stability properties of linear multivariable feedback systems with time-delays are studied. The control schemes considered are conventional feedback control and Smith Predictor control. Depending upon the known perturbation structures, tight conditions are given which guaran

The problem of the optimal control of systems modeled by transfer functions containing pure time delays is transformed to a differential-difference equation formulation. The optimal feedback control law analogous to that of Kalman [ 121 for undelayed systems is applied to these problems. The case wh

In this article we study the global stability in reaction-diffusion models for single-species population growth under environmental toxicants with or without time delays. The existence and uniqueness of a positive steady-state solution are established in those models. It is shown that as long as the
