函数模板 meaning in English
function templates
Examples
- This kind of controller is easy to design and operate , and has improved convergence rates and less overshoot than pid controller , but has stable error . in order to improve the properties of the fuzzy controllers , fine - tune - rule fuzzy controller , fine - tuned parameter fuzzy controller and fuzzy - pi controller were designed respectively based on the simple fuzzy controller . then fuzzy logic inferential system is established by using toolbox of fuzzy logic in matlab7 . 0 . secondly , in simulink6 . 0 , through the instance of the template of s - function , the module of s - function for optimizing fuzzy control and corresponding control model are constructed , and the parameters of simulation are set
这种控制器易于设计、实现方便,较传统pid控制有更快的响应速度和更小的超调,但其存在静态误差;为了进一步提高模糊控制器的控制特性,在此基础上分别设计了可调整控制规则模糊控制器、参数自整定模糊控制器和模糊- pid复合控制器;然后利用matlab7 . 0模糊逻辑工具箱图形用户界面建立模糊逻辑推理系统,在simulink6 . 0系统仿真设计平台中通过实例化s函数模板创建旨在优化模糊控制的s函数功能模块,并构建模糊控制系统框图模型,设置系统仿真参数,最终对系统进行动态仿真。 - I study mainly the storage of record and object , and bring forward the method of storage when the instance of object is embodied inside of record . 3 ) in the aspect of indexing , i presented a method that is generalized b - tree ( gbt ) and combining technique of founction template of c + + build the universal algorithm of queries , insert and delete . 4 ) finally , i analyze deeply and improve the query processing system of ormdbms , and confirm performance algorithm of linking and queries based on relational database . management system ( rdbms )
在系统结构和特性中分析了系统所采用的两层体系结构，并且详细探讨了在设计和实现数据库时所涉及到的几个主要问题：支持复杂对象、类型扩充、继承机制和规则系统等；在存储机制的讨论中，主要研究了记录和对象以及包含了对象实例记录的存储方法；在索引技术研究中，本文提出了类属b树的索引方法，通过c + +的函数模板技术给出了通用类属b树查询、插入及其删除的基本算法；最后，文章以关系数据库为基础，深入分析并改进了在对象关系多媒体数据库中的查询处理系统，确定了选择和连接操作的具体算法。
