摘要:
在机载外辐射源雷达不纯净参考信号条件下,参考通道中的多径与回波匹配得到的干扰将降低空时自适应处理的目标检测能力,而网格失配问题严重影响了干扰的估计性能.本文针对网格失配下的机载外辐射源干扰抑制问题,提出一种基于局部搜索的干扰估计算法.该算法在干扰稀疏观测模型的基础上构建全局距离-多普勒字典,从中选择与干扰相匹配的全局网格点;然后以该全局网格点为中心,对多普勒平面精细划分来构建局部多普勒字典,并选择与干扰更匹配的局部网格点;最后估计干扰的距离-多普勒像以实现干扰抑制,克服不纯净参考信号的影响.仿真结果表明,所提算法可降低网格失配导致的抑制性能损失,有效提高不纯净参考信号下空时处理的目标检测能力.

摘要:
针对传统CSAMT三维正演场源奇异性及无穷边界处理等问题,提出了一种基于等效场源的CSAMT三维无限元快速高精度正演模拟算法。首先,通过精确计算场源附近一定范围内网格节点的电磁场,实现水平电偶极源的精确模拟;然后,采用无限元代替传统截断边界条件,通过有限元-无限元耦合法和并行直接求解方法,实现基于等效场源的CSAMT三维快速精确求解。均匀半空间模型测试结果验证了算法的正确性。同时,以趋肤深度公式为基础,开展了场源等效模拟的最佳范围研究,数值结果表明对于场源的等效加载范围最好不低于1.5倍趋肤深度。

摘要:
It is significant to boost the construction of small hydropower stations in mountainous areas due to the source water's abundance and big fall. However, the instability of small hydro increases the power quality problems such as harmonic and inter-harmonic when synchronizing and brings about lots of difficulties in the rapid development. To solve the power quality problems is an important bottleneck in the development of small hydro. This paper bases on the currently available harmonic and inter-harmonic detection methods, focuses on the specific situation of small hydro synchronization and puts forward an add-window interpolation FFT algorithm. Meanwhile, comparisons among several situations adopting different window functions are made and simulations in MATLAB are processed. The results show that the add-window interpolation FFT algorithm can overcome the picket fence effect, frequency spectrum leakage and aliasing. When choosing window function, employing Harming window is more appropriate for harmonic and inter-harmonic detection arose by the synchronization of small hydro. ©2013 Asian Network for Scientific Information.

With the different colourful gradient operators, the binding algorithm has been applied to image segmentation. In order to make the color image of the edge detection operator in line with the resolution of the human eye on the image information and prevent the problem of the over-detection of the edge of the insensitive area, the paper has proposed the combination algorithm using the adaptive color image and value estimation method of color threshold. The construction has comprised with the partial chromatic aberration of the brightness mask and the contrast sensitivity threshold. The paper has proposed visual impact of the weight factor to solve some problems of image segmentation. It is combined with the brightness and colors' information. The color of partial background is the spatial frequency of human vision. The experiment results have shown that the proposed algorithm can accurately detect the image edge and effectively resist noise image interference. ©2013 by CESER Publications.

摘要:
In order to increase the accuracy ofpower quality disturbance detection in noising environment, this study puts forward a denoising algorithm ofpower quality distu?bance based on self-adapting to neutral fuzzy control. It establishes a structure with double-input and single-output neural network fuzzy system. Meanwhile, it presents the principle of denoising and makes a simulation analysis on disturbance circumstances with colored noise such as harmonic wave, voltage sag, voltage swell, voltage interruption etc. The results indicate that the proposed algorithm can well remove the signal-disturbing noise in grid. The waveform is visual clarity;the process ofanalyzing and calculating is simple and fast;the data got from calculation is few, which make the disturbance denoising ofpower quality more practical. ©2012 Asian Network for Scientific Informaction.

摘要:
岸电电源是在船舶制造、远洋钻井平台、码头等方面应用非常广泛的稳频稳压电源,但它对输出电压波形的稳态精度、动态性能等要求较高。通过对现有各种逆变控制方法进行研究和比较,在建立和分析岸电电源三相逆变器数学模型的基础上,针对它在旋转αβ坐标系下的特点,提出了一种神经网络内模控制和PID控制相结合的复合波形控制策略。建立了3层BP神经网络内部模型,并将其作为三相逆变器的内部模型,预测实际输出,采用PID控制器在线修正、补偿内部模型与三相逆变器之间的模型失配。对比仿真和实验数据,可以看出:当系统接阻性负载或整流性负载时,该控制方法所得的稳态电压误差和输出电压的谐波畸变率均小于其他控制方法,表明该策略控制下的岸电电源稳态精度高、输出波形质量好,具有一定的工程实用价值,能很好地应用于岸电电源逆变波形控制。
