in the hardware design, the paper completes modules ’ design like outside memory, patulous a / d, patulous d / a, rs232 communication, ecan communication, led control, keyboard control, distant control, emulation, reset, logic voltage switch, dsp supply power regulate and ac-dc power circuit, as well as room layout design like anterior panel, back panel etc . and dsp transfers data with peripheral equipments except outside memory using serial ports . besides, the whole circuit is configured in interrupt response . thus, it can meet system demand as well as take full advantage of tms320f2812 ’ s hardware resource . in the software design, the paper finishs programs like the interface programms intercommunicates with people, the distant control program, ad and da modules ’ control program, in addition, the paper select the velocity and acceleration state-feedback algorithm and is written in the program . the software design uses dsp integrate exploiting environment named ccs2.2 of ti inc . as software instrument, and programs with the combination of c language and assembly language . moreover, in order to maintenance or modify the software expediently and shorten software ’ s exploitation time, the design adopt software modularization technique . finally, some air cylinder experiments are carried out to proved that the pneumatic controller is very practical 在硬件设计中,本文完成了片外存储器扩展、a/d扩展、d/a扩展、rs232通信接口、ecan通信总线接口、液晶显示控制、键盘控制、远程控制、仿真、复位、逻辑电平转换、dsp工作电源校正电路和ac-dc电源等模块设计以及控制器前面板、后面板等的空间布局设计。其中dsp与除外部存储器的外围设备之间的数据传送全部采用串口通信,同时系统电路配置成中断响应方式,这样既满足了系统要求,又充分利用了tms320f2812的硬件资源。在软件设计中,本文完成了人机界面功能模块、远程控制模块、ad扩展模块、da扩展模块、速度和加速度状态反馈的控制算法的程序设计。
different from other researches, autoore uses the proposed java semantic model as input data, and gives a tree-liked, hierarchical structured and semantic cluster set . the clustering method is based on a minimum spanning tree that represents the software system . the clustering objective function is designed according to the software modularization metric and cognition psychology theory 抽象是autoore的核心,它首次采用对象系统的语义关系抽取数据为输入,利用基于mst表示的、聚集目标结合了程序认知心理学理论的软件聚集方法,得到一个具有丰富语义的、组织为树状的、分层的聚集集合。
