First obtain that the factors control the level attitude are the roll angle and the yaw angle  and infers the algorithm of flight route  according to the attitude and the route restraint  and infers the computation algorithm of attitude  produce shortest aircraft level flight road map which through the giving route position on the software surface. According to this algorithm  it may control and plan the aircraft level flight  through to limit of the aircraft security attitude and the route position. 2010 IEEE.   Innovative EDL GNC scheme for precise and safe mars landing missions (EI CONFERENCE) 会议论文 60th International Astronautical Congress 2009, IAC 2009, October 12, 2009 - October 16, 2009, Daejeon, Korea, Republic of Li S.; Peng Y.; Liu Y.; Zhang L. 收藏  |  浏览/下载：40/0  |  提交时间：2013/03/25 Future mars missions plan to land the more massive spacecrafts on the higher altitude and hazardous region  the landers should have the capability of high-precision autonomous navigation guidance and control (GNC) and automatic obstacle detection and avoidance to explore the scientific but hazardous region. The traditional deep space network (DSN) based GNC mode used in the Mars entry  descent and landing (EDL) phase has no ability to meet this goal  so the novel EDL GNC scheme is required to achieve the precise and safe Mars landing. This paper proposes the innovative Mars EDL GNC system scheme and the emphases are focused on the EDL navigation guidance and control with high landing accuracy and autonomous obstacle detection and avoidance.   A study of the jacking system for ferroalloy electric furnace electrode based on linear motor controlling (EI CONFERENCE) 会议论文 9th International Conference on Electronic Measurement and Instruments, ICEMI 2009, August 16, 2009 - August 19, 2009, Beijing, China Peng X.; Jiwei Z. 收藏  |  浏览/下载：21/0  |  提交时间：2013/03/25 The current jacking system for the hydraulic electric furnace electrode in Jilin Ferroalloy Factory is adopted the hand control in electrode jacking plan  against this situation  a structure  which can adapt the linear stepping motor to control the digital valve for adjusting the location of the hydraulic system has been raised  and the current system would realize automatic control to the electrode jacking by this way  at the same time  and by Fuzzy-PID control method the linear stepping motor would be controlled to obtain precise positioning in control. The hydraulic system controlled by digital valve have been described and analyzed in jacking feasibility and stability. What's more  it is inspected and verified that the adjustment of this system has high precision and quick response. 2009 IEEE.
