Abstract
In this chapter, a robust control design based on the quadratic approach was presented. The performance requirements are considered following two different paths. The first one consists of locating the closed-loop system poles in a disk, the parameters defining the disk (centre and radius) being chosen in a way that ensured good transient behaviour.
The second one consists of defining a cost function (quadratic) and minimising a cost upper bound, leading to the well-known guaranteed cost design. In fact, these two means to express performance are considered simultaneously in this chapter.
The derived conditions expressed in terms of parameter dependent Riccati equations can be solved with available numerical powerfull techniques.
