The direct drive structures which are widely applied in many servo control fields. Matlab Xilinx System GeneratorR toolbox based on Fixed-Point Arithmetic is used to design the digital PI controller using DSP architecture  plot the responses of the control system and generate the VHDL source code. The control system model consists of a digital PI  a real LABTM  and a real absolute Inductosyn  encoder to rpm and position blocks. Through loading generated codes in process of the simulation that built by the digital discrete model  it is verified that the rising time of current loop is only 1.2ms  and rate loop is 8ms  overshoot is rarely 4.2%. Finally  the comprehensive positioning accuracy of system can reach up to 5 arc sec  and the rate jitter achieves 5% with the 4 arc sec accuracy absolute Inductosyn.

The laser is driven by the digital constant current source module  and the apparatus has good human-machine interaction performance on account of set the parameters intelligently. The function such as operation mode  output power  output pulse width and pulse cycle could be easily set through the TFT touch screen. The application software could transmission the log data to the computer by the USB interface in order to check and study the records later. 2011 IEEE.   Design of programmable near infrared cold light source (EI CONFERENCE) 会议论文  OAI收割 2011 International Conference on Electronics and Optoelectronics, ICEOE 2011, July 29, 2011 - July 31, 2011, Dalian, China 作者:  Fu Q.;  Wang B.;  Wang B.;  Wang R. 收藏  |  浏览/下载：31/0  |  提交时间：2013/03/25 In the near infrared spectroscopy  detector of Charge-coupled Device requires very high stability for light source. We design the cold light source in the measurement of near infrared spectroscopy. Cold light source consists of high-power op amp OPA549 high current constant current source and proportion integral differential (PID) control algorithm. As is shown in the experimental results  the method is better  the overshoot is very small  the stability is excellent in the process of soft-start. While light intensity was able to meet the requirements of near-infrared instruments to measure. 2011 IEEE.
