摘要：

In any control loop, time delays appear and can produce unexpected changes in the controlled system performances. In this paper, the impact and relevance of the input delays in a control system are analyzed from two viewpoints. First, the possible positive effect of the delays in either avoiding oscillatory input/output plant coupling or reducing the strong control action in discrete controlled systems. Second, relating the maximum allowable delay in the control implementation with the control effort in modifying the dynamic behavior of the plant. Some conclusions emphasize these concepts in control engineers education. Copyright (C) 2000 IFAC.
