Three-Axis Virtual Flight Motion Simulator are used to simulate the attitude of missile in simulation system with hardware-in-loop  so its performance influenced the result of simulation directly. This paper mainly analyzed the factors which influenced the performance of a three-Axis virtual flight motion simulator which we are used now in the lab  then analyzed the entire simulation system's error caused by these factors through numerical simulation method. By analysis we can see that bandwidth is the main factor influenced the precision of simulation systems with hardware-in-loop  mechanical device installation error and measurement error may also cause some errors of the systems at the same time.   Stabilization and tracking precision improved based on disturbance observer (EI CONFERENCE) 会议论文 2011 2nd International Conference on Mechanic Automation and Control Engineering, MACE 2011, July 15, 2011 - July 17, 2011, Inner Mongolia, China Sun G.; Zhu M.; Jia H. 收藏  |  浏览/下载：18/0  |  提交时间：2013/03/25 Based on the kinematics of semi-strapdown seeker  the framework coordinate of the semi-strapdown seeker is established and the optical axis stabilization equation of semistrapdown seeker is deduced based on product of exponential (POE) formula. The stabilization control principle block diagram of semi-strapdown seeker is shown based on the stabilization equation. The main influence factors of the stability precision are pointed out  such as friction disturbance  velocity measurement noise and missile disturbance. For the sake of improving the stabilization precision and tracking precision  disturbance observer was proposed in the inner loop of semi-strapdown seeker servo-control system. The low frequency external disturbance and high frequency velocity measurement noise are effectively restrained by the disturbance observer as shown in hardware-in-loop simulation  and optical axis stabilization precision and tracking precision are greatly improved. 2011 IEEE.   Research of real-time control and calibration on laser energy simulator for optoelectronic confrontation HWIL system (EI CONFERENCE) 会议论文 2011 International Conference on Electronics, Communications and Control, ICECC 2011, September 9, 2011 - September 11, 2011, Ningbo, China Wang J.-J. 收藏  |  浏览/下载：13/0  |  提交时间：2013/03/25 In the paper  real-time control and calibration on laser energy simulator is studied  which is based on Optoelectronic confrontation hardware-in-loop (HWIL) simulation test system. The control of the laser energy is necessary in simulation system  and it is vital to make the test successfully. The laser energy simulator simulates the attenuation process and the changing of laser energy by the continuous rotation of Glan prism. To get high accuracy of laser power outdoor  the accurate calibration of the rotation position and the attenuation process in energy simulator is necessary. We apply dual calibration on the laser energy simulator  and the feasibility was proved by the calibration data. 2011 IEEE.   Optical axis stabilization of semi-strapdown seeker based on disturbance observer (EI CONFERENCE) 会议论文 2011 International Conference on Information and Automation, ICIA 2011, June 6, 2011 - June 8, 2011, Shenzhen, China Sun G.; Zhu M.; Yin S.; Jia H. 收藏  |  浏览/下载：18/0  |  提交时间：2013/03/25 Based on the kinematics of semi-strapdown seeker  the framework coordinate of the seeker is established. The optical axis stability equation of semi-strapdown seeker is deduced by using attitude transformation matrix. Then  the stability control principle block diagram of semi-strapdown seeker is shown based on the stability equation. The main factors that influence the stabilization precision are pointed out  such as friction disturbance  velocity-measuring noise and missile disturbance. In order to improve the stabilization precision  disturbance observer was proposed in semi-strapdown seeker stability control. The low frequency external disturbance and high frequency velocity measurement noise are effectively restrained by the disturbance observer as shown in hardware-in-loop simulation  and optical axis stabilization precision is improved nearly 20 times and 5 times due to two different frequencies with same amplitude. 2011 IEEE.   Design and implementation of Electro-optical Countermeasure Hardware-in-the-loop simulation system based on HLA (EI CONFERENCE) 会议论文 2010 3rd International Conference on Advanced Computer Theory and Engineering, ICACTE 2010, August 20, 2010 - August 22, 2010, Chengdu, China Yu G.; Li Y.; Guo J.; Cui S.; Wang J.

As an important sub-system in simulation test system  the reality is the focus of the simulation system. The construction of the computer control system for laser warning based on HLA Distributed Simulation. By combining the outer clock and time stamp for data frame  data interaction is triggered by outer clock  the simulation process is propelled. The simulation terminal devices are also controlled by the outer clock. The simulation test is done by the above method. The result shows that the data interaction time less than lms  and it meet the need of reality for control  so it is effective. 2010 IEEE.
