Objective:The causes of failure of Luque rod fixation for th e s coliosis were analyzed.

Dyeing control based on robust H_∞ multi-step prediction;

Parameter tuning for nonlinear robust controller with high gain observer;

Designing method of robust dynamic inversion for 3-D terminal guidance law;

The iterative learning control of a class of nonlinear system with the robustness of initial state;

It can obtain some good and bad points of these two methods separately according to aspects such as forecasting accuracy rate,the speed,robustness,understanding easily and so on with the concrete instance data.

To our best knowledge,the only multivariable design method in the open literature that can optimize robustness is μ synthesis method,which we utilize to add optimal robustness to good command response of aircraft longitudinal control system.
