Abstract:Multivariable PI controllers for systems with time delays can be tuned with applied optimization using different formulations for the objective function. Strategies based on H ∞ and H 2 system norms impose the need of approximation of the time delays by Padé functions. On the other hand, optimization of a performance index based on signal norms rather than system norms are more direct and straightforward to formulate, although more time-consuming. In this paper, it is analysed how the different ways to formula… Show more
