概述了飞行控制律设计的几种主要方法。通过对比自适应飞行控制律和程序调参飞行控制律,总结 了处于飞行控制器设计领域主导地位的程序调参飞行控制律的主要优点和不足,并就程序调参技术在现代飞控领 域的研究现状及其在某先进飞机中的实际应用进行了介绍。最后,针对现代飞机的飞行特点,展望了程序调参飞 行控制律今后可能的发展方向。 (Summarizes the flight control law design of several major method. By comparing the adaptive flight control law and procedure parameters tuning flight control law is summarized The flight controller design field is in the leading position of the program and flight control law of the main advantages and disadvantages, and the process parameters tuning technology in the modern flight control broughtThe research status and domain in some advanced aircraft in the practical application are introduced in this paper. Finally, the modern aircraft s characteristics, and looks forward to the program and fly Line control law could in the future development direction.)

传感器网络由大量能量有限的微型传感器节点组成.因此,如何保证在足够覆盖监测区域的同时延长网络的寿命,是一个需要解决的重要问题.为了达到这一目标,一种广泛采用的策略是选出部分能够足够覆盖监测区域的节点作为工作节点,同时关闭其他冗余节点.提出了一个数学模型,使得只要已知监测范围和节点感知半径的比值,就可以计算出达到服务质量期望所需要的节点数量.需要指出的是:与大部分研究覆盖的文献不同,该研究不基于节点的位置信息,因此可以极大地降低硬件成本,并且减少节点获得和维护位置信息的开销.模拟实验结果表明:在随机部署条件下,服务质量期望与实验所得到的实际覆盖度的误差不大于服务质量期望的2％ 而对于相同的服务质量期望和实际覆盖度,计算所得的工作节点数量与实验所得的工作节点数量的误差小于计算数量的5％,这表明推导出的节点数量与服务质量期望之间的关系与模拟实验的结果相吻合.该结果可以广泛应用于传感器网络的节点部署、拓扑控制等领域中.()

关于DFIG的低压穿越能力的研究。对以后实现低压穿越做一些探索性的工作(Along with the sharp increase in the proportion of wind power supply some areas the impact of Large-scale wind farms for the stability of regional power grid is more significant. The research on low voltage ride-through (LVRT) of wind power system based on doubly-fed induction generators (DFIG) becomes a hot issue. In this paper ,Firstly introduces the concept of low voltage ride-through technology, The standards of LVRT of some European countries are presented, And then analyses and compares the kinds of common realize low voltage ride- technology and improve control strategy. The transient characteristics of DFIG when the grid voltage sagging.)
