The methods integrates optimally feed forward and feedback control  and adopts acceleration delay compensation based on velocity delay compensation  then achieves servo control of O-E theodolite effectively. Furthermore  Angular acceleration sensor is applied as information resources  and adaptive filter is formed to provide with feed forward control signal in the methods. For double closed loop servo control system of O-E theodolite  the location correction loop and velocity correction loop are analyzed and designed. Simulation and experimental results show that comparing with traditional methods  this servo control methods can improve significantly tracking precision and stability of O-E theodolite. 2010 IEEE.   Embedded system of time uniform based on DSP (EI CONFERENCE) 会议论文  OAI收割 2010 International Conference on Computer, Mechatronics, Control and Electronic Engineering, CMCE 2010, August 24, 2010 - August 26, 2010, Changchun, China 作者:  Li N.;  Liu C.-X.;  Liu C.-X.;  Chen J.;  Guo L.-H. 收藏  |  浏览/下载：23/0  |  提交时间：2013/03/25 We introduced a design method of DSP-based System of time uniform  which combine the GPS and the Compass to calibrate the time. The system can use UTC (Coordinated Universal Time) of the GPS or the Compass for time base  to generate absolute time and different frequency of synchronous signals. We used DSP (Digital Signal Processor) to calculate the satellite information which includes the UTC time. After getting the UCT time information  put it into the CPLD (Complex Programmable Logic Device) for correction of time delay and serialization to output. Meanwhile  we divided 1PPS (one-pulse-per-second) signal of the GPS and the Compass into 20Hz  50Hz  and 800Hz synchronous signal. And we analyzed the precision of time and frequency. To conclude  the uncertainty of system absolute time is less than 100ns  the uncertainty of system synchronous signals is less than 20ns. This system is easy and flexible for use  stable and reliable in performance. 2010 IEEE.   Application of multi-sensors parallel fusion system in photoelectric tracing (EI CONFERENCE) 会议论文  OAI收割 2008 International Conference on Optical Instruments and Technology: Optoelectronic Measurement Technology and Applications, November 16, 2008 - November 19, 2008, Beijing, China Cheng G.-Y.; Cai S.; Gao H.-B.; Zhang S.-M.; Qiao Y.-F. 收藏  |  浏览/下载：23/0  |  提交时间：2013/03/25 To solve the real-time and reliability problem of tracking servo-control system in optoelectronic theodolite  a multisensors parallel processing system was proposed. Misdistances of three different wavebands were imported into system  and then prediction was done in DSP1 to get the actual position information. Data fusion was accomplished in PPGA imported by multi channel buffer serial port. The compound position information was used to control the theodolite. The results were compared with external guide data in DSP2 to implement correction of above calculation  and then were imported to epistemic machine through PXI interface. The simulation experiment of each calculation unit showed that this system could solve the real-time problem of feature level data fusion. The simulation result showed that the system can satisfy the real-time requirement with 1.25ms in theodolite with three imaging systems  while sampling frequency of photoelectric encoder was 800 Hz. 2009 SPIE.
