中文摘要：

针对未知相对度系统，提出了一种一阶D型迭代学习控制律的设计方法．通过对具有未知相对度的被控系统串连和并联一个一阶子系统，可构造一个相对度为1的虚拟系统．该虚拟系统在一阶D型迭代学习控制律的作用下，能够完全跟踪期望轨迹．从而实现被控系统在一定误差范围内给定轨迹的渐近跟踪，D型迭代学习控制律的增益不依赖于被控系统的参数．仿真实例验证了方法的可行性与有效性．

英文摘要：

First, this paper provides a formal description of business behavior. Based on the description, the paper provides the business process description method based on ECA rules in detail. As the result, the paper discusses the relationships among the activities of one business behavior and the relationships among the different business behaviors. The result shows that the method can make the description of the business process more clearly and correctly, at the same time, it can enhance the capability of adapting the changes.
