Model predictive control(MPC) is widely applied in industry and safety is the most important issue. One measure for safety control is a fault tolerant control which controls plants safely even when a fault occurs. In many cases, effects of fault are represented by effects of unknown disturbances and to suppress such effects of unknown disturbances is an effective method of fault tolerant control. Hence, this paper considers a control to suppress the effects of disturbance for model predictive control. Also frequently fault occurs at measurement of outputs and feedback loop is cut and this causes the output being unstable and plant being dangerous. If the poles of controller are designed to be stable, then the unstable output is avoided and a method to specify poles of the controller being stable is also obtained for the fault tolerant GPC. Hence this paper gives a control scheme (1) to suppress the effects of disturbances and (2) to prevent output being unstable when feedback is cut. To ensure these controls, this paper proposes two control schemes, (1) to derive a mathematical expression of the effect of disturbance, (2) to design stable poles of the controller. To design the controller poles, this paper uses an extended generalized controller by state space coprime factorization approach. The extended controller brings additional poles in the closed-loop. Hence, to design fault tolerant control, (3) as the third control schemes, this paper also derives mathematical expressions of the cancelled poles of the closed-loop systems and the poles of the controller. Once, these expressions are obtained, then these poles are easily designed by selecting design parameters in the controller.","PeriodicalId":325361,"journal":{"name":"2018 International Conference on Advanced Mechatronic Systems (ICAMechS)","volume":"39 6","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120922841","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}

In order to solve the problem that image dehazing algorithms have poor adaptability, which will occur contrast distortion after restoration or cannot eliminating the influence of dense haze, a self-adaption single image dehaze method based on clarity evaluation is proposed to effectively recover the visual effects of the scene. The innovation points of this paper lied in that, first, the haze image is disposed separately according to average value, standard deviation, average gradient, information entropy and other clarity judgment features of the input image; then, the method of self-adaption image quality evaluation and coding decision is introduced to the dehaze results, to output the best effects obtained through comparison of many methods; finally, the clarity judgment is carried out again to output the final results. Experimental results demonstrate that the proposed method can achieve a better dehazing effect, and its chromaticity, luminance and contrast are improved to a certain extent. The universality of dehaze method is further improved.","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":"130074976","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}

The main origin for these effects have been attributed to the presence of two compounds found in tea, caffeine and L-theanine with caffine being related to attention, energy, motivation, self-confidence, alertness and concentration and L-theanine related to relaxation. In this study, a wearable functional Near-Infrared Spectroscopy (fNIRS) device was used to monitor neural activity. The device operating at a wavelength of 810 nm could detect absorption changes in total oxyhemoglobin (HbO) due to neural activity and the current study focused on addressing changes in attention under the consumption of green tea and other beverages. In this pilot study, a total of 6 Japanese undergraduate students (3 males and 3 females) participated and the cognitive tasks included multiplication (M) and word generation (W) game in English. It was found that during both the multiplication and word tasks, the relative decrease in total HbO was smaller for green tea in comparison to both control or no drink and other beverages for almost all the subjects. In conclusion, we suggest for the existence of a correlation between drink type and task performance and this could have implications not only in classrooms and but also form the basis of studying the cognitive effects of different drinks available in the market.","PeriodicalId":325361,"journal":{"name":"2018 International Conference on Advanced Mechatronic Systems (ICAMechS)","volume":"149 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":"133271115","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}

The conditions for the system to be ASPR are given by (1) the system is minimum-phase, (2) the system has a relative degree of 1, (3) the high-frequency gain of the system is positive. It is well recognized that, under the ASPR condition, one can easily design stable adaptive output feedback control systems and/or adaptive output tracking control systems which have simple structure utilizing only output of the controlled system. Under the ASPR conditions, the ASPR based adaptive output feedback controls including simple adaptive control (SAC) can reduce the number of adjusting parameters and can design the controller without the knowledge of the order of the controlled system. Therefore, the ASPR based adaptive output feedback controls have strong robustness with respect to system's uncertainties and disturbances so that several kinds of practical applications have been reported. Unfortunately, however, since there are many systems that have relative degree greater than one and/or is not minimum phase, most practical systems do not satisfy these ASPR conditions. One of the simple solution to overcome the problem is to introducing a parallel feedforward compensator (PFC). By introducing the PFC to the controlled system, the difficulty to control uncertain system is drastically alleviated via simple adaptive output feedback based on ASPR properties. In my talk, the basic design concept of the output feedback based adaptive control system is presented and the availability of the PFC is explained. The applicability of the output feedback based adaptive control is also shown with some application results","PeriodicalId":325361,"journal":{"name":"2018 International Conference on Advanced Mechatronic Systems (ICAMechS)","volume":"30 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":"116556553","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}
