Practical application shows that the system is reliable  designed the slip motor speed control system for packing rubber strip which is used in plastic steel door and window. The system  stable and higher precision of control. The system design provides reference for similar control system and builds the basis for the design of intelligent control system. 2010 IEEE.  32-bit embedded microprocessor LPC2136 as the control core  PWM speed control  velocity feedback from tachogenerator  rubber strip position feedback from the CMOS camera  has proved that CMOS camera's image quality meets the engineering requirement   Microstructures and mechanical properties of Mg-2Y-1Mn-1-2Nd alloys fabricated by extrusion 期刊论文  OAI收割 materials science and engineering a-structural materials properties microstructure and processing, 2010, 卷号: 527, 期号: 16-17, 页码: 4383-4388 Fang DQ; Bi GL; Wang LM; Li GY; Jiang ZH 收藏  |  浏览/下载：30/0  |  提交时间：2012/04/26 MASS-PERCENT ALLOYS  Y-ND ALLOY  TENSILE PROPERTIES  MAGNESIUM ALLOY  BEHAVIOR  X=0  DEFORMATION  ZK60   The effect of Si additions on the high-temperature oxidation of a ternary Ni-10Cr-4Al alloy in 1 ATM O(2) AT 900-1000 degrees C 期刊论文  OAI收割 Oxidation of Metals, 2008, 卷号: 69, 期号: 5-6, 页码: 299-315 S.
