EFFICIENT ALGORITHM FOR L∞-NORM CALCULATIONS

An efficient algorithm for L∞-norm calculations, implemented in the SLICOT Library, is described and compared with other available algorithms. The algorithm exploits the Hamiltonian structure of the computational problem and offers generality and flexibility. Continuous- and discrete-time, standard as well as generalized systems are addressed. Extensive comparisons with other L∞-norm solvers show that the generalpurpose SLICOT solver is the most efficient one, especially for standard continuous-time problems.
