	High gain observer for drag tracking in mars entry longitudinal guidance (EI CONFERENCE) 会议论文 OAI收割 2012 International Conference on Measurement, Instrumentation and Automation, ICMIA 2012, September 15, 2012 - September 16, 2012, Guangzhou, China Wu K.; Cui H.; Ma D.; Cui P. 收藏 \| 浏览/下载：29/0 \| 提交时间：2013/03/25 An extended high gain state and perturbation observer combined with feedback linearization was applied in drag tracking for Mars entry longitudinal guidance. The observer estimates the drag the drag rate and the perturbation due to model uncertainty and disturbance for drag tracking. Mars entry simulation was performed to assess the performance of the adaptive guidance law. The results demonstrate that the proposed guidance law is robust to model error and can recover the ideal performance of the feedback linearization control. Introduction In recent years the concept of pinpoint landing has been proposed (2013) Trans Tech Publications Switzerland.
	Adaptive control at launching using three loop autopilot (EI CONFERENCE) 会议论文 OAI收割 2011 2nd International Conference on Mechanic Automation and Control Engineering, MACE 2011, July 15, 2011 - July 17, 2011, Inner Mongolia, China 作者: Zhang Y. 收藏 \| 浏览/下载：25/0 \| 提交时间：2013/03/25 In order to guarantee the precise initial flight trajectory control the missile disturbance of large disturbance torque three loop adaptive autopilot was researched. The characteristics of the projectile and three loop autopilot instruction formation characteristics were analysed. From equivalent pitching angle of lateral acceleration feedback loop combined with the instruction of generalized error autopilot structure was simplified and three loop autopilot adaptive control law and stability were designed. The test data show that when disturbance torque was 600Nm the attitude angle generalized error was -4.4. In the time lasted about 15s late trajectory accuracy was within 1.0.Three loop autopilot adaptive control law was able to control the disturbance of initial trajectory and adapt to dynamic characteristics changes control system stability. It was the initial trajectory accurate solution method of flight. 2011 IEEE.
	The application of the discrete sliding mode control based on state observer in aerial camera (EI CONFERENCE) 会议论文 OAI收割 2nd Annual Conference on Electrical and Control Engineering, ICECE 2011, September 16, 2011 - September 18, 2011, Yichang, China 作者: Zhang X.; Zhang X.; Zhang X. 收藏 \| 浏览/下载：17/0 \| 提交时间：2013/03/25 A discrete sliding mode control scheme based on state observer is designed for DC torque motor. Aim on the problem of control chattering and steady-state chattering caused by discrete sliding mode control method adaptive reaching law is proposed Non-chattering and stability are made an analysis. The aerial camera is chosen as an experimental platform and the discrete sliding mode controller with adaptive reaching law is applied to the drawtube system the value of acceleration can be observed on line. The experiment results show the control scheme can effectively eliminate chattering and also make the drawtube system achieve better dynamical performance. 2011 IEEE.
	Adaptive sliding mode control for airborne Opto-Electronic platform servo system (EI CONFERENCE) 会议论文 OAI收割 7th International Conference on Machine Learning and Cybernetics, ICMLC, July 12, 2008 - July 15, 2008, Kunming, China Wang C.-X.; Liu J.-H.; Shen H.-H.; Dai M. 收藏 \| 浏览/下载：21/0 \| 提交时间：2013/03/25 The novel presents an adaptive reaching law sliding mode controller to slove a class of uncertain systems.The Airborne Opto-Electronic Platform sliding model is employed to represent a class of complex uncertain system. The control is based on reaching law control. Discrete time implementation of the sliding mode control strategy is considered in the paper since it is more appropriate for practical applications. It is shown that the robustness of the sliding mode control method is constrained by sampling time. Design of the adaptive reaching law based on a discrete expotential reaching law concept is given which to design a new sliding mode controller based on Lyapunov stability theory. The global asymptotic stability is guaranteed. An example with simulation results is given to illustrate the effectiveness of the proposed method. 2008 IEEE.
