Abstract :
Consider an H∞-norm optimization problem where the goal is to minimize the H∞-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
