However, the electromagnetic actuators affect both the relative trajectory and attitude motion, complicating related studies on issues of invariant shape design and formation control. This paper mainly focuses on the formation keeping control for three-craft electromagnetic formation with triangular invariant shape on the basis of a 6-DOF full nonlinear dynamic model. Considering the high nonlinearity, strong coupling, model uncertainties and external disturbances, a combined control scheme involving feed-forward and feedback control components is proposed. The feed-forward component is obtained through desired invariant shape design which is complicated by the superposition and coupling effects of any two distinct magnetic dipoles. The feedback component is realized utilizing linear feedback controller based on the LQR method and active disturbance rejection control based on the extended state observer. Finally, the numerical simulation is presented to verify the feasibility and validity of the proposed 6-DOF control scheme.","PeriodicalId":6623,"journal":{"name":"2018 IEEE CSAA Guidance, Navigation and Control Conference (CGNCC)","volume":"206 1","pages":"1-7"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76066507","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since the research on implementation of UAV target tracking system lack the tracking control along depth direction in image coordinate, and the research on 3D visual servo tracking control based on state feedback controller is hard to implement, we propose to utilize the face detection module to provide with the position and size data of the target face and then track the face along 3D directions based on a modified mean shift tracking algorithm and PD controller.

In addition, compared with the traditional Allan variance’s object of analysis, in this paper, the method is carried out in the frequency domain for every IMF.

It can automatically schedule the flight path according to the optimal conditions and correct the orbit deviation by changing the direction of the thrust vector to achieve the precise orbit. However, the problem is that the attitude of the rocket into orbit’s time must be determined by the thrust vector direction and cannot be predetermined. Otherwise, the deviation of the last moment of the thrust vector may make the accuracy of the iterative guidance difficult. Based on the traditional IGM, a terminal attitude constraint Iterative guidance method(TACIGM) based on parabolic feature is proposed for the problem that the traditional IGM can not carry on the attitude constraint. The results show that the TACIGM can meet the accuracy of the traditional IGM, but also can meet the high accuracy of the orbit attitude, and It can adapt to the variation of the attitude angle. The method will have a high engineering application value.","PeriodicalId":6623,"journal":{"name":"2018 IEEE CSAA Guidance, Navigation and Control Conference (CGNCC)","volume":"45 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83068360","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
