With the new concept,the problem of variable structure control of 2D discrete system is transferred to the problem of seeking a sliding model with good sporting character and attractability. The concrete design schemes of the imitative sliding model and variable structure controller are also put forward. And the concrete expression of the time T in ε-neighborhood of reaching switch manifold is obtained. The difficulty of applying the existing methods to MIMO systems is overcome.

在新概念之下，将2D离散系统的变结构控制问题转化为寻找一个既具有良好的运动品质又具有吸引性的滑动模问题，给出了滑动模及变结构控制器的设计方案，并且获得了达到切换流形的ε领域的时间T的具体表达式，克服了已有方法难以应用到多输入—多输出系统上的困难。

Pass N second inspection, did not discover a problem 2 it is server overtime, search the Time Out option of Web Site, discovery is really 120, the rapture in the heart, should become 600, not effective, still have a problem, the wrong page that jumps out namely is not me inside the project, and the Error attribute of the project does not have coupling go to an alone file?

经过n次检查，没有发现问题 2是服务器超时，查找web site 的time out 选项，发现真的是120，心中狂喜，该成了600，不起作用，还有一个问题，就是跳出来的错误页面不是我项目里面的，并且项目的error 属性没有联结到一个单独的文件上去？
