This disturbance observer consists only of integrators. In the typical disturbance observer, the differentiator causes high frequency noise. However, the disturbance observer without differentiator does not have this trouble. The use of this disturbance observer allows to expand the pass band of the low pass filter, and it is predicted that the ability of estimating disturbance would be improved. Implementation of a newly created second-order lag system disturbance observer without differentiator is proposed. In order to implement the disturbance observer, it is necessary to obtain the nominal model of the plant. However, it is troublesome to use another control technology. Therefore, parameters are adjusted with implementation of disturbance observer. The effect by applying disturbance observer is verified. Different adjustment methods are also compared.","PeriodicalId":325361,"journal":{"name":"2018 International Conference on Advanced Mechatronic Systems (ICAMechS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129896973","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}

However, reference frequency fluctuation in a large range will significantly decrease the harmonics suppressing performance of PIMR-type repetitive control. In this paper, a PIMR-type repetitive control with frequency adaptation is proposed to cope with the frequency fluctuation. The improved PIMR-type repetitive control uses fractional delay filter which can be approximately realized by finite impulse response (FIR) filter. The varying fractional delay filters ensure that the resonant frequencies can match the actual reference frequency and harmonic frequencies. The simulation results show that the proposed PIMR-type repetitive control can track grid reference signal and suppress harmonic signals, and have good error convergence rate under grid frequency fluctuation.","PeriodicalId":325361,"journal":{"name":"2018 International Conference on Advanced Mechatronic Systems (ICAMechS)","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130212117","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}

This algorithm took into account the local visual information of the image, proposed an AHLBP texture extraction method with adaptive threshold. The method overcame the limitations caused by a single fixed threshold in texture extraction. In order to mine image texture information in depth, textures were extracted from the three color channels in the HSV color space. Then the paper fully used the texture to establish an accurate and complete object model as a description of the object, and achieved object tracking. Experimental results show that the algorithm can effectively improve the accuracy and stability of tracking and make the tracking algorithm has a better robustness.","PeriodicalId":325361,"journal":{"name":"2018 International Conference on Advanced Mechatronic Systems (ICAMechS)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126653776","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}

Therefore, distance measure based on binocular vision technology has become a hot research topic. This kind of distance measure technology has relative high measure accuracy as well as lower hardware cost. However, due to the adoption of inexpensive binocular cameras, the tangential and radial distortions exist. Thus, the distortion will in turn bring measure error. In other words, measure accuracy of system will decline. This paper, we propose a stereo calibration method for binocular cameras. Camera calibration method is employed to obtain the intrinsic and extrinsic as well as distortion parameters of cameras. Stereo calibration is conducted to correlate the left and right image plane. Rectification method is to make left and right image plane satisfy epipolar constraint. Because after rectification, we can reduce computation of matching correspond feature points in left and right image as well as improve system response speed. The average reprojection error can be controlled within 9 pixels.","PeriodicalId":325361,"journal":{"name":"2018 International Conference on Advanced Mechatronic Systems (ICAMechS)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128260911","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}
