The paper introduces a kind of method about current loop control system which is based on position and velocity dual-closed loop control system. This method improves effectively the performance of velocity closed loop control system and amplifies the gain of low frequency. The results show applying these control methods  the influence of the torque ripple has decrease 50% and the compensation rate precsion has promoted double. 2011 IEEE.   Control strategies and error compensation methods of high precision gyro stabilized platform (EI CONFERENCE) 会议论文  OAI收割 30th Chinese Control Conference, CCC 2011, July 22, 2011 - July 24, 2011, Yantai, China Deng K.; Cong S.; Shen H. 收藏  |  浏览/下载：27/0  |  提交时间：2013/03/25 Based on the principle of gyroscope and the structure of gyro stabilized platform  this paper gives the analysis and comparison of control strategies for stable platform included classical PID control  and three kinds of advanced strategies: Fuzzy Control  Sliding Mode Variable Structure Control and Active Disturbance Rejection Control. The compensation methods for stable platform's error are also discussed and evaluated based on the sources of error  especially for the non-linear friction and gyro drift. The paper provides the reliable methods for recognizing and improving the accuracy of gyro stabilized platform from the control strategies and error compensations. 2011 Chinese Assoc of Automation.   The research on servo control technology of O-E theodolite based on angular acceleration sensor (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 Wei L.; Jin G.; Juan C. 收藏  |  浏览/下载：22/0  |  提交时间：2013/03/25 A new servo control methods for O-E theodolite is presented in this paper. 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.   Thermal difference analysis and athermalization design of infrared optical system (EI CONFERENCE) 会议论文  OAI收割 Optical Design and Testing IV, October 18, 2010 - October 20, 2010, Beijing, China 作者:  Zhang X.;  Zhang X.;  Zhang X. 收藏  |  浏览/下载：32/0  |  提交时间：2013/03/25 When infrared optical system works in a large temperature range  the thermal effect of optical lens and optical tube will produce image plane shift and lead to imaging quality deterioration. In order to eliminate the thermal aberration  the athermalization design principles of infrared optical system were introduced  and some commonly used methods of thermal difference compensation were described. Proceeding from single lens  the thermal difference caused by temperature changing was analyzed  and the relationship between temperature and focus shift was obtained. Considering optical tube thermal expansion  a set of equations to estimate the thermal difference of lens group was given. Finally  an infrared optical imaging system that can work under the temperature range of -40C to 60C was design according to athermal technique  in which a new mechanical passive temperature compensation was proposed. Through simulation  the athermalization design could make imaging plane shift the smallest. The simulation results coincided with the theoretical formula  and the design had reference value in engineering. 2010 Copyright SPIE - The International Society for Optical Engineering.   Dynamic compensation of Nonlinear sensors by a learning-from-examples approach 期刊论文  OAI收割 IEEE TRANSACTIONS ON INSTRUMENTATION AND MEASUREMENT, 2008, 卷号: 57, 期号: 8, 页码: 1689-1694 作者:  Marconato, Anna;  Hu, Mingqing;  Boni, Andrea;  Petri, Dario   |  收藏  |  浏览/下载：19/0  |  提交时间：2019/12/16 dynamic compensation  low power  microcontroller implementation  reduced-set methods  support vector machines for regression (SVRs)  wireless sensor networks (WSNs)   Analysis of a precise instrument for measuring reference level involute (EI CONFERENCE) 会议论文  OAI收割 Third International Symposium on Precision Mechanical Measurements, August 2, 2006 - August 6, 2006, Xinjiang, China 作者:  Zhang Y.;  Wang X.;  Wang X.;  Wang X.;  Wang L. 收藏  |  浏览/下载：29/0  |  提交时间：2013/03/25 Reference level involute is used for evaluating other involutes  but it is very difficult to measure reference level involute exactly. Nowadays the available methods for measuring precise involute include single base disc mode  electronic generation mode  and CNC three-coordinate mode. But measurement accuracy of the modes above is not suitable for reference level involute. A precise instrument for measuring reference level involute  double base discs instrument  is introduced. It is consistent with generation principle of the involute entirely. Besides having the advantages of single basic disc instrument  the instrument can remove Abbe error caused by the stylus  and has no pressure deforming. The instrument's structure is described. The main sources of measurement errors are analyzed and methods for compensation are presented. Finally  uncertainty of the instrument is given  which meets reference level involute test specification.
