In order to research the robustness of terminal area energy management(TAEM) trajectory for reusable launch vehicle(RLV),a method of trajectory robustness assessing based on nonlinear equations of motion was developed.

The robust trajectory tracking control strategy accounts for model errors and external disturbances using linear feedback theory for the non-linear system, which ensures system stability and li.

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.
