| 摘 要： | 针对一个特殊的系统进行建模。此特殊性可描叙为:控制系统为对密封管道中质量轻的物体(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U;输出为物体的高度。先后对PWM调压、风扇、空气管道和非线性红外线等环节建模,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,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。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: | 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.PWM regulator,fan,air pipeline,nonlinear infrared and other programs success... |
