Özet
According to some recent results, use of non-causal uncertainty blocks may be advantageous in the robust controller design of systems with multiple uncertain time-delays. In this work, performance and robustness improvements obtained by utilizing such an approach are presented. The flow controller design problem for networks with multiple uncertain time-delays is considered as a case study. It is shown that higher performance levels and larger stability margins are, in general, obtained by using non-causal uncertainty blocks. A number of simulations, which illustrate the time-domain performance improvement, are also presented.
