A Global Optimization Approach to Scalar H_2/H_∞ Control

摘要

Various approaches to the mixed H_2/H_∞ control problem are proposed in the literature. The solution is often obtained by means of classical techniques (i.e. solving a Riccati problem) or by means of convex opti- mization procedures. With the aim to synthesize a fixed-structure controller for an uncertain plant, a glo- bal optimization approach to a single-input single- output (SISO) H_2/H_∞ problem is proposed.
