Photoelectric theodolite of U type with main visual axis and auxiliary visual axis shoots images and inverse images of marks to obtain system error data. Error is less than 0.4 second by comparing error data of auxiliary visual axis with error data of main visual axis and the precision of two methods is identical. It has been validated that the method of error measurement of photoelectric theodolite of T type is right. 2012 IEEE.  vertical axis error  Azimuth orientation error  elevation zero error   Modeling and variable structure control of a vehicle flexible manipulator (EI CONFERENCE) 会议论文 10th World Congress on Intelligent Control and Automation, WCICA 2012, July 6, 2012 - July 8, 2012, Beijing, China Sxu Y.; Qiao Y.; Wang Z.; Liu K.; Li Y. 收藏  |  浏览/下载：19/0  |  提交时间：2013/03/25 In this paper  the mathematical modeling and the application of a new trajectory tracking control technique for hydraulic-driven rigid-flexible manipulator are concerned. To get a closer dynamic behavior of the real system  both the flexible manipulator linkage and the actuator dynamics are considered. The exact dynamic model of flexible manipulator is derived using Lagrange principle and assumed modes method. The partial decoupled dynamic equation is derived using nonlinear decoupling feedback control method. The whole dynamic model is established by a driven Jacobin matrix  which represents the coupling between hydraulic servo system and mechanical system. A variable structure controller with inverse dynamics is designed for trajectory tracking. To weaken the chattering of control signal  saturation function is used to instead of sign function. The experimental results investigate the effectiveness of the proposed approaches. 2012 IEEE.   Internal Model Control Of Three-phase Four-leg Active Power Filter Based On Online LS-SVM ANN Inverse System Method 会议论文 作者:  Qi, Hong;  Shao, Zhenhua 收藏  |  浏览/下载：10/0  |  提交时间：2019/11/21 shunt active power filter (SAPF)  inter model control(IMC)  least squares support vector machine(LS-SVM)  artifical neural networks(ANN)  inverse system method   Decoupling Control of Magnetically Suspended Rotor System in Control Moment Gyros Based on an Inverse System Method 期刊论文 IEEE-ASME TRANSACTIONS ON MECHATRONICS, 2012, 卷号: 17, 页码: 1133-1144 作者:  Fang, Jiancheng;  Ren, Yuan 收藏  |  浏览/下载：4/0  |  提交时间：2020/01/06 Control moment gyro (CMG)  decoupling control  exact linearization  internal model control (IMC)  inverse system method  magnetic bearing  robust controller
