| Abstract: | The problem of tightly bounding and shaping the frequency responses of two objective functions Ti(s)( i=1,2) associated with a closed-loop system is considered. It is proposed that an effective way of doing this is to minimize (or bound) the function max {∥T1(s)∥ ∞, ∥T2(s)∥∞} subject to internal stability of the closed-loop system. The problem is formulated as an H∞ control problem, and an iterative solution is given |
