The literature for \mathcal H_\infty control is essentially identical to the one we gave in the previous chapter on analysis of robustness. In particular, we stick to our primary textbook [1], in which the material is discussed in the forty-page Chapter 9.

While discussing the analysis of robustness in the previous chapter, we omited discussion of structured uncertainties using the structured singular values (SSU, mu, \mu). Similarly here we did not delve into the extension of that framework towards control synthesis. Purely because of time constraints. But should you find some time, have a look at section 8.12, which discusses the methodology called \mu synthesis.
