Video transmitting robustness in the wireless multimedia e-commerce systems;

Reduction model of robustness for distributed artificial immune system;

Moreover,the method is of strong robusticity on background disturbance.

A method to determine the admissible set of PID controller (parameters) with robust performance;

Model uncertainty bound of first order lag process with dead time and IMC controller design for robust performance;

The results from the simulation and test show that the robust performance and the robust stability of EMBs are guaranteed by the guaranteed cost control method, and the contradiction between large global mo.

On the other hand,the robustness was necessary to tolerate the system operating near the stability limit.

A design method of H ∞ robust controller based on Smith predictor is presented, where the robustness problem of time delay process is ingeniously shifted into that of delay free process, so that the analysis and synthesis are simplified and the fractional approximation of time delay is avoided.

The results of simulating experiments on the effect of scaling factor choice on the robust performance of a fuzzy controller are presented.

The practice application indicates that the auto disturbance rejection controller doesn’t rely on the precision model of the system,at the same times its disturbance-rejection and robust performance are all better than the traditional PID controller.
