班组遥控武器站模糊自适应滑模位置控制器设计

针对班组遥控武器站位置伺服系统发射冲击力矩大、负载变化范围广和伺服精度要求高等特点,提出了一种模糊调节的位置伺服系统滑模控制策略。该策略选用了一种新型的带有积分的滑模面,模糊调节部分采用单输入双输出的结构,应用模糊规则调节新型快速终端滑模型趋近速率来削弱滑模抖振。分别进行了常值负载干扰、系统参数摄动、时变负载干扰和跟踪误差仿真实验。仿真实验表明,该控制策略的稳定性和伺服跟踪性很好,对参数摄动和负载干扰的鲁棒性很强。

Pairwise model discrimination with applications in lifetime distributions and degradation processes

Reliability data obtained from life tests and degradation tests have been extensively used for purposes such as estimating product reliability and predicting warranty costs. When there is more than one candidate model, an important task is to discriminate between the models. In the literature, the model discrimination was often treated as a hypothesis test and a pairwise model discrimination procedure was carried out. Because the null distribution of the test statistic is unavailable in most cases, the large sample approximation and the bootstrap were frequently used to find the acceptance region of the test. Although these two methods are asymptotically accurate, their performance in terms of size and power is not satisfactory in small sample size. To enhance the small‐sample performance, we propose a new method to approximate the null distribution, which builds on the idea of generalized pivots. Conventionally, the generalized pivots were often used for interval estimation of a certain parameter or function of parameters in presence of nuisance parameters. In this study, we further extend the idea of generalized pivots to find the acceptance region of the model discrimination test. Through extensive simulations, we show that the proposed method performs better than the existing methods in discriminating between two lifetime distributions or two degradation models over a wide range of sample sizes. Two real examples are used to illustrate the proposed methods.     

Analysis of a new vehicle scheduling and location problem

We consider a container terminal discharging containers from a ship and locating them in the terminal yard. Each container has a number of potential locations in the yard where it can be stored. Containers are moved from the ship to the yard using a fleet of vehicles, each of which can carry one container at a time. The problem is to assign each container to a yard location and dispatch vehicles to the containers so as to minimize the time it takes to download all the containers from the ship. We show that the problem is NP‐hard and develop a heuristic algorithm based on formulating the problem as an assignment problem. The effectiveness of the heuristic is analyzed from both worst‐case and computational points of view. © 2001 John Wiley & Sons, Inc. Naval Research Logistics 48: 363–385, 2001     

论国防动员中军事征用制度的立法完善

新颁布的《国防动员法》为我国今后军事征用活动的开展提供了重要的法律依据,是军事征用法制发展的里程碑。文章提出,与现行军事征用的立法价值实现及实践要求相比,我国军事征用法律制度仍存在需要完善之处。应科学设立军事征用主体、不断完善军事征用程序和军事征用补偿机制。

在单频单历元GPS短基线定向中,由于模糊度解的不可靠性,导致部分定向结果不可靠.在基线约束GPS短基线定向算法的基础上,提出一种动态准实时定向滤波算法.该算法根据载体的运动特性,判断并剔除解算错误的值,并在解算错误或解算失败的历元进行插值.实测数据处理表明,该方法能够将基线约束算法的定向正确率提高5～10%左右,使基线约束GPS短基线定向算法的稳定性得到进一步提高.
