The aim of this experiment was to investigate the ameliorative effect and molecular mechanism of tilapia head glycolipid(TH-GL)on indomethacin(IDM)-induced gastric ulcer in male Sprague Dawley(SD)*** gastric ulcer model was established by oral administration of 30mgkg^(-1) IDM after 7 days of TH-GL or omeprazole(OME)administration in *** the macroscopic gastric injury symptoms,gastric mucosa protective factor cyclooxygenase 1(COX-1),cyclooxygenase 2(COX-2),prostaglandin E_(2)(PGE_(2)),the levels of oxidative stress,and inflammatory cytokine expression levels in the rats were *** experimental results showed that multiple ulcers appeared on the gastric surface of the rats in the model *** to the model group,TH-GL significantly alleviated gastric ulcers and reduced the gastric damage index in *** addition,TH-GL significantly promoted the expression of constitutive enzyme COX-1 while inhibited the expression of inducible enzyme COX-2,and make PGE2 maintain at normal ***-GL also inhibited oxidative stress and inflammatory responses,increased superoxide dismutase(SOD)activity and glutathione(GSH)content,decreased the level of malondialdehyde(MDA)and the content of pro-inflammatory *** conclusion,these results suggested that TH-GL could maintain the expression levels of COX-1 and PGE2 while inhibit the expression of COX-2 in the gastric of rat and then prevent IDM-induced gastric ulcer,which may be related to the regulation of oxidative stress and inflammatory ***,TH-GL might be a new option for the prevention of gastric diseases induced by IDM.

For a permanent magnet synchronous motor(PMSM)model predictive current control(MPCC)system,when the speed loop adopts proportional-integral(PI)control,speed regulation is easily affected by motor parameters,resulting in the inability to balance the system robustness and dynamic performance.A PMSM optimal control strategy combining linear active disturbance rejection control(LADRC)and two-vector MPCC(TV-MPCC)is ***,a mathematical model of a PMSM is presented,and the PMSM TV-MPCC model is developed in the synchronous rotation coordinate ***,a first-order LADRC controller composed of a linear extended state observer and linear state error feedback is designed to reduce the complexity of parameter tuning while linearly simplifying the traditional active disturbance rejection control(ADRC)***,the conventional PI speed regulator in the motor speed control system is replaced by the designed LADRC *** simulation results show that the speed control system using LADRC can effectively deal with the changes in motor parameters and has better robustness and dynamic performance than PI control and similar *** system has a fast motor speed response,small overshoot,strong anti-interference,and no steady-state error,and the total harmonic distortion is reduced.

第37届中国控制会议

作者： bohui wang Xinpeng Fang Bin Zhang School of Aerospace Science and Technology Xidian University Department of Electrical Engineering University of South Carolina

This paper addresses the general framework and problems for cooperative control for industrial multi-agent *** a fact that there are many results on cooperative control over the past few years, the application requirement of cooperative control, especial in industrial networked system, should be considered by a more proper view. This paper forms the initial framework and problems to analyze the development of the recent years. Some recent works are given and discussed. Finally,some interesting issues are proposed.

超声流量计的回波信号中通常存在噪声干扰,导致回波信号难以准确定位。为滤除超声波回波信号中的噪声,提出了一种基于优化变分模态分解(VMD)算法的信号去噪方法。所提方法首先利用互信息准则的信息熵将遗传算法与VMD相关联。然后,将样本熵作为适应度函数,自适应性地优化VMD算法中的参数组合。最后,对原始信号进行分解,利用相关系数计算出有效信号,并将有效信号进一步去噪后进行重构。仿真结果表明,所提方法能有效滤除超声波回波信号中的噪声并且能够完整的保留有用信号。

通过对网络入侵的相关知识进行研究,提出了一种基于本体模糊映射和特征分析相结合的网络入侵检测模型;在研究中首先对知识元或数据信息集经过训练形成本体知识库,然后对已知入侵模式的特征知识元或数据信息集进行挖掘,形成特征库;当待测数据集开始检测时,先抽取其知识本体,对其本体和本体知识库中的本体元进行模糊映射,相似度在系统安全阈值范围内的,属于正常数据集,否则,置其入数据评估集,进行特征库匹配,匹配度低的数据信息集属于异常数据给予用户提示,予以报警;在待测数据集检测结束后,对本体知识库和特征库实时更新;该模型通过数据信息集的训练形成自有本体库,避免了数据噪音干扰,提高了检测效率和预警率。
