驾驶员诱发振荡的抑制方法

对电传操纵系统驾驶员诱发振荡（ＰＩＯ）的现象进行了分析，指出了舵回路速率饱和是造成ＰＩＯ的主要原因，并有针对对给出了一种非常规的用于解决饱和非线性问题的程序控制方法。这种方法主要是通过舵回路反馈的状态信息来改变驾驶杆输入信号的放大系数，从而达到有效抑制ＰＩＯ的目的，同时用Ｈｕｒｗｉｔｚ稳定判据进行了机理分析，最后给出了仿真验证结果，证明该方法是简单而有效的。     

温度翘曲应力对机场刚性道面寿命的影响

分析了目前中国民航机场刚性道面的设计过程,指出在设计过程中忽视温度应力的影响不合理。参照公路水泥混凝土路面温度应力计算方法并根据Miner定律研究了温度翘曲疲劳损耗对于机场刚性道面影响规律,即温度翘曲疲劳损耗随板厚、地基反应模量的增大而增大,随着混凝土设计强度的增加而降低。然后提出采用设计寿命的影响因子nt/Nt评价温度翘曲疲劳损耗对于机场刚性道面设计寿命影响的方法并提供了相应的机场刚性道面板厚度设计流程图。最后提供了一个考虑温度翘曲应力的刚性道面设计实例,为工程应用提供参考。

Development of an improved ground-based prototype of space plant-growing facility

Based on a formerly developed ground-based prototype of space plant-growing facility, the development of its improved prototype has been finished, so as to make its operating principle better adapt to the space microgravity environment. According to the developing experience of its first generation prototype and detailed demonstration and design of technique plan, its blueprint design and machining of related components, whole facility installment, debugging and trial operations were all done gradually. Its growing chamber contains a volume of about 0.5 m³ and a growing area of approximate 0.5 m²; the atmospheric environmental parameters in the growing chamber and water content in the growing media were controlled totally and effectively; lighting source is a combination of both red and blue light emitting diodes (LED). The following demonstrating results showed that the entire system design of the prototype is reasonable and its operating principle can nearly meet the requirements of space microgravity environment. Therefore, our plant-growing technique in space was advanced further, which laid an important foundation for next development of the space plant-growing facility and plant-cultivating experimental research in space microgravity condition.

Weeden and Chow: Commentary from a legal perspective

The paper, ‘Space sustainability through the sustainable management of common-pool resources: a framework and potential policies’ by Brian Weeden and Tiffany Chow, researches Long-Term Sustainability issues (LTS) from the perspectives of both economics and governance, focusing on analyzing Elinor Ostrom's principles, and puts forward the main elements for a management regime. Their paper will be helpful for the international community to understand the importance of LTS, to further discussions in this field and even to shape a framework for tackling LTS. On the other hand, some of the principles raised by Ostrom still need to be clarified and deliberated throughout the international community. This commentary will analyze some of Ostrom's principles from the perspective of the 1967 Outer Space Treaty (OST) and put forward the values LTS should encompass based on an analysis of its relations with provisions in the OST.

Robust adaptive fault-tolerant control of a tandem coaxial ducted fan aircraft with actuator saturation

This paper is concerned with the robust adaptive fault-tolerant control of a tandem coaxial ducted fan aircraft under system uncertainty, mismatched disturbance, and actuator saturation. For the proposed aircraft, comprehensive controllability analysis is performed to evaluate the controllability of each state as well as the margin to reject mismatched disturbance without any knowledge of the controller. Mismatched disturbance attenuation is ensured through a structured H-infinity controller tuned by a non-smooth optimization algorithm. Embedded with the H-infinity controller, an adaptive control law is proposed in order to mitigate matched system uncertainty and actuator fault. Input saturation is also considered by the modified reference model. Numerical simulation of the novel ducted fan aircraft is provided to illustrate the effectiveness of the proposed method. The simulation results reveal that the proposed adaptive controller achieves better transient response and more robust performance than classic Model Reference Adaptive Control (MRAC) method, even with serious actuator saturation.
