摘要：混合式步进电机由于其优越的运动性能而被广泛应用于高精尖场合,但由于步进电机存在失步,且转速越高转矩越小的情况限制了其应用环境。为此,本文区别于传统的步进电机开环控制和驱动方式,对五相混合式步进电机采用闭环反馈和控制器控制。首先,采用磁场定向控制(Field-Oriented Control,FOC)策略,介绍了FOC控制方法和相关控制器基本原理;随后,根据五相混合式步进电机本体的数学模型,提出了适用于五相混合式步进电机的空间矢量脉宽调制(Space vector pulse width modulation,SVPWM)算法,设计了PI控制器,基于趋近率的滑模控制器,超螺旋滑模控制器,针对电机闭环反馈系统,建立了相对应五相混合式电机的转速、电流双闭环反馈控制系统以实现对电机系统的动态控制;最后,在Matlab/Simulink中搭建了五相混合式步进电机控制系统,对控制系统和控制器进行可行性验证。结果表明,采用上述方法提高了电机系统的鲁棒性和高速运行带载能力。

摘要：Electronic structures in two kinds of boron structures are investigated by the first-principle density func- tional theory （DFT） calculations. One structure is from theoretical prediction, and the other is from experimental in- vestigation. Binding energy calculations suggest that the boron structure designed from theory is more stable than that made by experiment. Elastic constants calculations show that both structures are mechanically stable. The electronic structure results show that the theoretical designed structure exhibits semi-metal behavior, while the other structure exhibits metMlic character. No magnetic phenomenal is discovered from them. All the calculations are carried out by the first principles calculation through the MatC1oud platform, which is developed by our research group.

摘要：对330MW等级直接空冷机组乏汽的利用与电蓄热锅炉调峰联合运行系统进行了介绍,对直接空冷机组乏汽供热与电蓄热调峰联合运行方式下的经济性进行了分析。由于电力辅助服务的运营,电热矛盾越来越突显,提高乏汽供热机组的灵活性尤为重要。从经济性、供热能力、调峰能力等方面对直接空冷机组乏汽供热与电蓄热调峰联合运行方式开展特性分析及调整优化试验研究。结果表明,影响该路线经济运行的主要因素是机组调峰深度和报价,其次是机组运行背压,增汽机影响最小。在不调峰工况下,提高机组高背压供热能力,控制增汽机在最佳设计条件运行,保证供热煤耗率较低运行,在调峰工况下,根据调峰深度和报价平衡机组供热负荷,在标煤单价较低情况下适当降低调峰申报价格,保证争取更大调峰电量;在标煤单价较高条件下分配好高背压+增汽机与调峰锅炉热负荷,根据热负荷比例申报调峰报价。

摘要：In order to find novel antifungal agents with good activity and aqueous solubility, a series of SYN-2869 analogues containing a pyridine ring were synthesized and evaluated for their in vitro antifungal activity and water solubility. The results indicated that some compounds showed potent activity against six pathogenic fungi. In particular, the analogue 17a having an isobutyl substitution on the triazolone exhibited significant broad spectrum antifungal activity. In addition, the water solubility of compound l？a was sufficiently improved over SYN-2869.

摘要：以某金矿废石破碎成5 mm以下的碎石和全尾砂为研究对象,在制备成膏体充填料浆的条件下进行了不同参数下充填体单轴抗压强度、抗拉强度实验,开展了单因素、多因素拟合分析及相关性检验,确定了各影响因素与充填体强度之间的关联度,探究了各因素对膏体充填体强度的影响规律;利用改进的MATLAB神经网络建立了料浆质量浓度(X_(1))、灰砂比(X_(2))(指质量比,下同)、砂石比(X_(3))、养护龄期(X_(4))对充填体强度(单轴抗压强度(Y_(1))、抗拉强度(Y_(2)))影响的预测模型。结果表明:充填体强度与各参数之间呈多元线性函数关系,灰砂比是影响充填体强度的主要因素,养护龄期和砂石比次之,料浆浓度最小;充填体强度随充填浓度、养护龄期和灰砂比的增大呈增长趋势,随砂石比的增大呈减小趋势;建立的充填体强度函数模型在预测该金矿单轴抗压强度(Y_(1))、抗压强度(Y_(2))中适应性强、收敛速度快而且精度高,为后期充填采矿强度需求设计提供了依据。
