Abstract :
This paper discusses the synthesis of fixed-architecture controllers that guarantee either robust H2 or H∞ performance. The synthesis is accomplished by solving a Riccati equation feasibility problem resulting from mixed structured singular value theory with Popov multipliers. It is seen that the numerical algorithm for robust H∞ performance is much more computationally intensive than that for robust H2 performance. The results are illustrated by designing robust controllers for a benchmark problem
