A new way to implement system on a chip is provided by the advent of FPGA. Based on Verilog HDL and the Actel Fusion AFS600 FPGA chip  the speed closed-loop control system of DC motor was designed by using options of combining the top-down thinking and the bottom-up method. PID control algorithm  encoder signal processing and PWM waveform generation etc were realized by the system. The results show that the system structure is simplified and the stability and reliability are improved. A solution of system on a chip is realized to some extent. It has extensive application value in engineering practice. 2011 Trans Tech Publications.   Experimental warming induces degradation of a Tibetan alpine meadow through trophic interactions 期刊论文  OAI收割 JOURNAL OF APPLIED ECOLOGY, 2011, 卷号: 48, 期号: 3, 页码: 659-667 Li, Guoyong; Liu, Yinzhan; Frelich, Lee E.; Sun, Shucun 收藏  |  浏览/下载：30/0  |  提交时间：2012/11/09 alpine meadow  bottom-up and top-down control  global warming  Tibetan Plateau  trophic interaction   Environmental mechanism of change in cyanobacterial species composition in the northeastern part of Lake Dianchi (China) 期刊论文  OAI收割 FRESENIUS ENVIRONMENTAL BULLETIN, 2007, 卷号: 16, 期号: 1, 页码: 82-90 作者:  Xing, Wei;  Huang, Wen-min;  Liu, Yong-ding;  Li, Dun-hai;  Shen, Yin-wu 收藏  |  浏览/下载：72/0  |  提交时间：2010/10/13 physical factors  chemical factors  cyanobacterial  species composition  canonical correlation analysis (CCA)  bottom-up control  top-down control  Lake Dianchi
