In order to detect the imbalanced fault as soon as possible, an imbalanced fault characteristics analysis method is applied based on image processing. A diagnosis method combining the modified sparse autoencoder (SA) and softmax regression (SR) is applied to process images and detect the imbalanced fault on the blade of MCT. The modified SA is used to extract the features and SR is used to classify them. The data of images are used to monitor whether the blade is attached by benthos and its corresponding degree of imbalance. Experiments show that the applied diagnosis method can achieve higher accuracy in the application of diagnosis of blade imbalanced fault compared with the traditional PCA feature extraction algorithm.","PeriodicalId":226586,"journal":{"name":"2018 33rd Youth Academic Annual Conference of Chinese Association of Automation (YAC)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126301073","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}

An optimal restoration model with an overall matching degree is established. Finally, this paper uses discrete ABC algorithm to solve the problem.

The parameter uncertainty and external disturbance are included in the system model, meanwhile the controller design is implemented based on the finite-time concept. Firstly, a novel nonsingular terminal sliding surface which is suitable for the time-delayed fractional-order T-S fuzzy systems is proposed. It is proved that once the state trajectories of the system reach to the proposed sliding surface, they will be converged to the origin within a given finite time. Secondly, in terms of the established terminal sliding surface, a novel fractional-order sliding mode control law is introduced, which can force the closed loop dynamic error system trajectories to reach the terminal sliding surface over a finite time. Finally, using the Lyapunov stability theorem, the stability of the proposed method are proved. The proposed method is implemented for control of time-delayed fractional-order Permanent Magnetic Synchronous Motor chaotic systems with uncertain parameter and external disturbance to verify the effectiveness of the proposed fractional order nonsingular terminal sliding mode controller.","PeriodicalId":226586,"journal":{"name":"2018 33rd Youth Academic Annual Conference of Chinese Association of Automation (YAC)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132504396","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 USVs have different driving directions and initial velocities, so the consensus algorithm is needed to coordinate the directions and velocities of the USVs. Firstly, based on the first order linear model of USVs, get the first order nonlinear differential equations of high frequency, and the simulate environment of USVs. Then, based on the Vicsek model, the consensus algorithm in cooperative control of USVs is proposed. Aiming at the problem that USV's angular velocity lags behind the rudder angle, this paper improves the traditional PD control method, and adopts cascade PID control.

The traditional method about urine sediment analysis depends on the observation of medical staff, in that case the workload is huge. With the development of image processing and pattern recognition techniques, the automation of urine sediment analysis can be realized. However, due to the complexity of the urine sediment micrograph, the accuracy and efficiency for automatic analysis are still in a low level somewhat. In this paper, an automatic detection method is proposed for the RBCs in the urine sediment micrograph. We borrow the concept of channel features which contain diverse type color channel features, and gradient magnitude channel features, etc. We adopt aggregate channel features which are variant and discriminative, combing improved soft-cascade adaboost classifier for RBCs detection in urine sediment micrograph.
