针对具有输入幅值约束的输入时滞机械系统,研究基于有向图拓扑的多智能体系统(multi-agent system,MAS)的一致性控制问题。对于只有部分智能体能够接收到理想信号的情况,提出一种观测器,使每个智能体都能观测到理想信号,并证明观测误差的指数收敛性。在控制器设计中,通过将系统的输入积分反馈到控制器中,消除输入延迟的影响;结合输入积分法和双曲正切函数,在解决输入延迟问题的同时限制控制输入幅值,并利用FMINCON函数优化控制参数。最后,利用李雅普诺夫方法证明控制目标的实现和闭环系统的渐近稳定性。仿真结果表明,所提出的观测器和控制器能够有效实现系统的一致性控制。

风能具有随机性和间歇性,准确可靠的风速预测对于风电场规划和电网运营规划至关重要｡本文提出VMD(variational mode decomposition,VMD)-SE(sample entropy,SE)-CEEMDAN(complete ensemble empirical mode decomposition with adaptive noise,CEEMDAN)-PSO(particle swarm optimization,PSO)-SVR(support vector regression,SVR)的组合分解短期风速预测｡首先是对VMD分解的子序列(intrinsic mode function,IMF)用样本熵(SE)判别方法对复杂度较高的子序列用自适应噪声的完备经验模态分解(CEEMDAN)进行二次分解,然后将两者分解后得到的序列用支持向量机(SVR)进行预测｡此外,为了找到更优的SVR参数,文中引入粒子群优化算法进行改进,并基于粒子群算法对SVR参数寻优,进而对某风电场进行短期风速预测,实验结果证明,VMD-SE-CEEMDAN-PSO-SVR模型的预测精度相对于其他模型更高。

An improved ensemble empirical mode decomposition(IEEMD) is suggested to process water quality spectral signals in order to address the issue that noise interference makes it difficult to extract and evaluate water quality spectral *** algorithm effectively solves the problems of modal mixing,poor reconstruction accuracy in the empirical mode decomposition(EMD),and a large amount of calculation in the ensemble empirical mode decomposition(EEMD).Based on EEMD,IEEMD firstly preprocesses the original water quality spectral signals,then performs Savitzky-Golay(S-G) smoothing on the decomposed effective intrinsic mode function(IMF) components,and finally reconstructs them to obtain the denoised *** sample data at different concentrations can be accurately analyzed based on the noise-reduced spectral *** this paper,three water quality parameters are used as research objects:benzene(C_(6)H_(6)),benzo(b)fluoranthene(C_(20)H_(12)),and chemical oxygen demand(COD).The original water quality multi-parameter(C_(6)H_(6),C_(20)H_(12),COD) spectral signals were subjected to denoising based on the IEEMD and the water quality multi-parameter joint detection *** signal-to-noise ratio(SNR) and the correlation coefficient(R^(2)) of the fitted curves obtained from the processing of the IEEMD were compared and analyzed with those obtained from the processing of the EMD and the *** experimental results show that the SNR of the spectral signals and the R^(2) of the fitting curve in three water quality parameters have been significantly ***,the IEEMD effectively improves the phenomenon of modal mixing,reduces the amount of calculation,improves the reconstruction accuracy,and provides an important guarantee for the effective extraction of multi-parameter spectral signals of water quality.

Objective： To observe the clinical efficacy of surrounding electroacupuncture needling for breast mass after acute ***： Thirty patients with breast mass after acute mastitis who conformed to the inclusion criteria were given surrounding electroacupuncture needling. Acupoint selection： 4-8 needles were needled around the mass and at Zusanli（足三里ST 36）,Sanyinjiao（三阴交SP 6）,Fengl6 ng（丰隆 ST 40） and Rugen（乳根 ST 18）. Electroacupuncture was performed at ST 36, SP 6 and ST 40. The above treatment was once a day. Treatment for 7 times was considered as 1 course of treatment, and 3 weeks were free from treatment between courses. Color ultrasound in breast was used to examine the breast mass before the next course of treatment, treatment can be terminated if the mass disappeared, otherwise, treatment should be continued. Three courses at most were ***： After 1-3 courses of treatment, 16 patients were cured, accounting for 53.3%（16/30）; markedly effective： 8 cases, accounting for 26.7%（8/30）; effective： 4 cases, accounting for 13.3%（4/30）; ineffective：2 cases, accounting for 6.7%（2/30）.Conclusion： Surrounding electroacupuncture needling for breast mass after acute mastitis was effective clinically.
