利用线性化反馈方法，设计滑模控制器。利用这种技术，设计了一种自适应神经控制器。(The use of feedback linearization method, the design sliding mode controller. With this technology, design of an adaptive neural controller.)

说明：  蚁群算法是一种用来寻找优化路径的概率型算法。这种算法具有分布计算、信息正反馈和启发式搜索的特征，本质上是进化算法中的一种启发式全局优化算法。(Ant colony algorithm (ACO) is a probabilistic algorithm for finding optimal paths. This algorithm has the characteristics of distributed computing, positive information feedback and heuristic search. It is essentially a heuristic global optimization algorithm in evolutionary algorithm.)
