 Abstract: In this paper, we propose an improved method for computing the $\mathcal{H}_\infty$ norm of linear dynamical systems that results in a code that is often several times faster than existing methods. Our approach uses standard optimization tools to rebalance the work load of the standard algorithm due to Boyd, Balakrishnan, Bruinsma, and Steinbuch, with the aim of minimizing the number of expensive eigenvalue computations that must be performed. Unlike the standard algorithm, our improved approach can also calculate the $\mathcal{H}_\infty$ norm to full precision with little extra work, and also offers some opportunity to improve its performance via parallelization. Finally, our improved method is also applicable for approximating the $\mathcal{H}_\infty$ norm of large-scale systems.
