摘要：新能源的迅速发展,使得大电网与分布式电源矛盾加剧.为了充分挖掘分布式电源为电网和用户所带来的价值和效益,微电网应运而生。微电网集成多个DG为一功率稳定的独立系统,有效解决了大规模DG的接入问题,其作为对单一大电网的有益补充,具有广泛应用的巨大潜力。本文根据微电网应用环境的不同对其进行了分类,分析了其不同的功能需求,提出了微电网的规划设计原则,列举了常用的微电网结构形式,并对微电网内电源的规划进行了阐述。最后,对一个实际算例进行仿真,仿真结果对微电网分布式电源并网规划提供了参考。

摘要：考虑目标机动和弹体动态特性,研究了导弹末制导律设计与实现问题。在切换函数的设计中应用增广比例导引的思想对目标的逃逸机动进行补偿;设计了变结构制导律,使得导弹的实际横向加速度具有增广比例导引的形式,来减弱弹体动态特性对制导精度的影响。在制导律实现过程中,应用高增益观测器对视线变化率进行了估计,同时通过将观测器进行二次扩张,实现了对目标机动加速度及其变化率的快速估计。最后进行了数值仿真验证,仿真结果说明了方法的有效性。

摘要：With the increasing of complexity of complex mechatronic products, it is necessary to involve multidis- ciplinary design teams, thus, the traditional customer requirements modeling for a single discipline team becomes difficult to be applied in a multidisciplinary team and project since team members with various disciplinary backgrounds may have different interpretations of the customers＇ requirements. A new synthesized multidisci- plinary customer requirements modeling method is pro- vided for obtaining and describing the common understanding of customer requirements （CRs） and more importantly transferring them into a detailed and accurate product design specifications （PDS） to interact with dif- ferent team members effectively. A case study of designing a high speed train verifies the rationality and feasibility of the proposed multidisciplinary requirement modeling method for complex mechatronic product development. This proposed research offersthe instruction to realize the customer-driven personalized customization of complex mechatronic product.

摘要：针对多相交错并联双向DC/DC变换器中的耦合电感器设计困难这一问题,提出具有普遍适用性的耦合电感器通用设计准则。以电感全部对称型耦合电感器的Buck+Boost型交错并联磁集成双向DC/DC变换器为例,研究变换器的Buck模态转换规律,得到变换器的等效稳态电感和等效暂态电感表达式,推导出变换器的稳态电流纹波和暂态电流响应速度与占空比、相数及电感耦合系数之间的关系。总结出交错并联双向DC/DC变换器中耦合电感的通用设计准则,按照这一准则,在给定占空比时,通过合理选择耦合电感器的耦合系数,可以既减小稳态相电流纹波又提高暂态输出电流响应速度。最后,通过实验验证了通用设计准则的正确性。

摘要：A new challenge has been brought by the rapid development of information technology to medical teaching, and the teaching reform of the medical education in China should be deepened for attaining a development. The core of deepening medical teaching reform is to break the traditional teaching model （i.e. giving a lecture）, and create a better classroom teaching situation by making full use of the modern teaching methods. In B-learning, the effective combination of the traditional teaching method＇ s advantages with the E-learning in a pure technical environment is advocated. In the task-driven teaching, a teaching design is made by students in a real or simulated real environment. In this paper, the effective combination of B-learning with the task-driven teaching model is introduced, so that the better teaching effect is achieved.
