Abstract

In this paper a new learning strategy is used for on-line tuning the control system of the ballistic missile. The gradient descent method technique is utilized to derive the on-line tuning laws of the robust controller, so that the robust performance of the system can be yielded. As the result of using this method, the old technique “gain schedule” that normally used in ballistic missile is replaced. The simulation result shows a good settling time, less or no overshoot and higher robustness were achieved. Moreover, the new tuning process is successful in the presence of high noise.
