	Study on infrared transparent radar double band-pass filter (EI CONFERENCE) 会议论文 OAI收割 2011 International Conference on Mechatronics and Materials Processing, ICMMP 2011, November 18, 2011 - November 20, 2011, Guangzhou, China Jia H. Y.; Feng X. G. 收藏 \| 浏览/下载：25/0 \| 提交时间：2013/03/25 To realize the functions of infrared transparent as well as radar double- pass Band A Y loop and Y slot compound element Frequency Selective Surface (FSS) structure is proposed which takes an infrared transparent inductive mesh as a substrate. The proposed structure is analyzed based on Galerkin spectral method. The transitivity of infrared (3um-5um) as well as the radar double passed band with two resonance frequencies (31GHz and 54GHz) is discussed. The result reveals that this structure has function of infrared transparent as well as stable radar double-band filter with effective shielding effect on S-band and C-band radar electromagnetic waves. The design with multiple passband is suitable for radar/IR composite guidance and it also offers a kind of new thinking way of design for multi-mode compound guidance systems. 2011 Trans Tech Publications.
	Design of control system of DC motor based on fusion FPGA (EI CONFERENCE) 会议论文 OAI收割 2011 International Conference on Mechatronics and Materials Processing, ICMMP 2011, November 18, 2011 - November 20, 2011, Guangzhou, China Zhu D. D.; Li H. W. 收藏 \| 浏览/下载：34/0 \| 提交时间：2013/03/25 Along with the development of microelectronic process it is possible to integrate a big system in one chip. 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.
