OPTIMAL POLE-PLACEMENT DESIGN FOR SISO DISCRETE-TIME-SYSTEMS

In this paper, we incorporate the placement of one real closed-loop po le into a compensator design framework based upon the Youla parameteri zation, duality theory, and linear programming, This framework has bee n used to design discrete-time compensators to solve the l(1) controll er design problem as well as other related time-domain optimization pr oblems. Previous work on these problems has focused on deadbeat system s, It is known that these can require high-order controllers. Part of the motivation for this work is to improve the tradeoff between contro ller order and performance over that using deadbeat control.
