A curve-shaping approach for determining bounds on H/sub /spl infin// performance under hard constraints

Consider an H/sub /spl infin//-norm optimization problem where the goal is to minimize the H/sub /spl infin//-norm of some transfer functions while subject to constraints on, for example, system bandwidth, peak sensitivity, or output variance. This paper presents a method of computing how these constraints limit the achievable performance. The approach involves optimally shaping the sensitivity function magnitude Bode plot.
