    摘要:

    论文是针对一个特殊的系统进行建模,此特殊可描叙为:控制系统为对密封管道中质量轻物体(以乒乓球为例)高度的控制。与密封管道密封相连接的是风机,需要控制模型底部的风扇来控制物体在管道中悬浮的高度,其中非线性红外线作为系统的测量仪器。即:输入为风扇的工作电压(;输出为物体的高度。论文中先后对PWM调压、风扇、空气管道和非线性红外线等环节的建模,并且提出了各个参量的获取方法。鉴于系统中涉及到多个小系统的非线性化建模和多个参量的获取,论文采用对系统进行线性化处理和利用外围仪器对参量的测取。本论文主要对系统建模提供了一种方法,其中对于各个小系统的建模都有可取之处。

    Abstract:

    This thesis aims at modeling a special system, which can be described in this way : The control system is to controling the light-quality object in the sealed pipeline.(eg: ping pang balls).The fan connected with the pipeline at the bottom of the model, is used to control the suspended -height of the object in it. And the Nonlinear Infrared is used as the measuring instrument. Thus ,the input is the fan's working volt; the output is the object's height. This thesis set models for PWM Regulator, fan, air pipeline ,Nonlinear Infrared and other programs successively. And give us a settlement of achieving the parameter of each programs . This article adopts linear treatment to settle the system and peripheral equipment to acquire the parameter. This essay mainly provides a method for the modeling system and it has redeeming feature for the model building of every mini system.
