Abstract : iterative learning control is an effective approach to the control of processes that are repetitive in nature . in this paper , an open - closed - loop pi - type iterative learning control scheme for the precise tracking control of a class of discrete nonlinear time - varying systems over a finite time interval is presented . the scheme updates control input with tracking errors of both current and last iterations simultaneously . sufficient and necessary conditions which guarantee the convergence of the scheme are given and then proved with inductive method . finally , the conditions are verified with simulation results 文摘:对于具有重复运动性质的对象，迭代学习控制是一种有效的控制方法.针对一类离散非线性时变系统在有限时域上的精确轨迹跟踪问题，提出了一种开闭环pi型迭代学习控制律.这种迭代律同时利用系统当前的跟踪误差和前次迭代控制的跟踪误差修正控制作用.给出了所提出的学习控制律收敛的充分必要条件，并采用归纳法进行了证明.最后用仿真结果对收敛条件进行了验证
The new thinking of editing is a creative thinking , through the anlaysis of its producting feature and the physics mechinism , we proposed the imaginative induction , the related comparision , the all - angel analysis , the backward thinking , which are productive method of the new thinking , and pointed out the function of the edit working 摘要编辑创新思维是一种创造性思维，通过对它的特征与产生的原因与生理机制的分析，采用的联想归纳法、相关类比法、全方位分析法、反向求新法等方法探讨了创新思维在编辑工作作用。
This thesis is a pragmatic analysis of physical education for the police students , including : police students , instructors , teaching facilities , contents , pedagogies , evaluations , etc . research methods include : bibliography , interview , comparison , logic and induction . in order to learn and gather more appropriate materials of peps , many questionnaires are conducted . 720 questionnaires have been sent out to 24 chinese police colleges and schools ( 10 questionnaires for peps instructors and 20 for police students ) . 159 questionnaires are for the instructors from 18 police colleges and schools have been sent back and 43 for police students have been sent back by 22 colleges and schools 研究方法主要有:文献资料法、专家访谈法、比较法、逻辑归纳法等。并根据研究需求,编制了我国公安院校警体课教学现状的调查问卷,在全国24所公安院校对广大师生发放,范围基本覆盖全国各地区,共发放问卷720份(每所院校警体教师10份,学生20份) 。教师问卷回收18所院校159份,学生问卷回收22所院校432份。
Next , according to the feature of different types of the industry chain , it is supposed that the manufacturing cost of suppliers and backward enterprises is known , with the method of the pricing of middle product , we set about the study on value attribution ? profit - distribution , and we use the regressively inductive method to find the scale of the profit - distribution . last , we use the situation of the industry chain of the data service inland and overseas to give evidence study 然后,基于不同电信增值业务产业链模式的特点,假设电信增值业务产业链上企业的生产成本为共同知识,本文运用中间产品定价的方式,研究不同类型的产业链模式下电信运营商与sp商的利益分配方式,并通过逆向归纳法(动态博弈)求解计算它们的利益分配比例,为现实电信运营商的发展提供理论支持。
This article , by means of scientific methods like induction and analysis , preceding from demonstrating the relationship between the system and teaching quality , after examining the management units ' functions and the system ' s intension , and then revealing how economic system reform , education system reform and university teaching system reform work with one another , identified and analyzed the existing problems in the current university teaching management system such as single methods , limited targets and imperfect assessment system , made a further discussion in theory on how and by what means university teaching management system can be perfected , and finally concluded that , as to teaching management , the ideology should be re - shaped , the units re - structured and the system perfected , and what is more , the teaching quality assessment and monitoying system should be estabiished 本文通过归纳法、分析法等科学研究方法，从探讨高校教学管理制度与高等教育质量的关系为出发点，分析了教学管理组织的职能、教学管理制度的内涵，重点剖析了当前经济体制改革、教育体制改革与高校教学管理制度创新之间的关系，从而提炼出目前高校教学管理制度中存在的管理方法单一、管理目标局限、评估体系不健全等一系列问题，并对如何完善高校教学管理制度以及采取怎样的完善措施进行了较为深入的理论探讨，得出了应重塑教学管理理念、重构教学管理组织、完善教学管理体制、建立教学质量评估制度与监控体系的结论。
