Finally, a quadratic regression equation is used to represent LTV system, and the GA and AIC are introduced to determine the structure of the parameter sub-model.

然后利用遗传算法和AIC确定参数子模型的结构，以获得最终用于表示LTV系统的二次回归方程。

Thus the control of nonlinear system could be studied via the linear time-varying (LTV) approximations.

本文介绍了基于迭代逼近的有限维非线性系统滑模控制方法。
