Lattice theory is a branch of mathematics.

格是离散数学的一个分支,超模函数对于函数的连续、可导性没有要求,因此更接近企业管理的实际问题。

In this paper, we discuss the learning control for nonlinear discrete system with delay. It is not necessary to use the desired input corresponding to the desired output and the desired state corresponding to the system in our learning algorithm and in the process of learning control. Therefore, our method needs less dynamics information of the controlled object than previous ones and only the qualitative Lipschitz condition is required.

摘 要:讨论了滞后非线性离散系统的学习控制问题,由于所给的学习算法及学习控制过程中,没有涉及和用到相应于理想输出yd的理想输入ud及对应于系统的理想状态xd,故对被控对象的动力学信息要求得很少,只是一种定性上的Lipschitz条件。
