In order to realize the humanized service from the robots, path planning and path tracking problems should be addressed according to typical and unique working environment. In this paper, the simplified four wheeled electric vehicle was chosen as our robot model, then the lateral controller was proposed based on the Lyapunov stability theory and linear control theory. Associated simulation models were constructed in the MATLAB environment, and simulation results show that the designing method of commad signals is reasonable and linear feedback controller can be used for robot trajectory tracking.","PeriodicalId":254705,"journal":{"name":"2019 Chinese Control And Decision Conference (CCDC)","volume":"1 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122115196","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}

It is extremely difficult to accurately diagnose it. To this end, this paper proposes an aero-engine fault diagnosis method based on kernel principal component analysis and wavelet neural network. The nuclear principal component analysis method is used to process the aero-engine original parameter data, extract its principal component features, reduce the parameter dimension, and construct the health state and fault state data sample set with the extracted principal component feature data. It is divided into training sample set and test sample set. The wavelet neural network fault diagnosis model is built by using the training feature data sample set. The diagnostic neural network fault diagnosis model is diagnosed and analyzed by using the test feature data sample set. At the same time, BP neural network is used to diagnose the same feature data sample set. In addition, the wavelet neural network fault diagnosis model is used to study the fault diagnosis technology of the original data. The research results show that the diagnosis results of the aero-engine fault diagnosis model based on kernel principal component analysis and wavelet neural network are obviously better than the diagnostic results of other methods used in this paper, and have good practical application value.","PeriodicalId":254705,"journal":{"name":"2019 Chinese Control And Decision Conference (CCDC)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131955665","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}

Most of state-of-the-art methods use hand-crafted features and bag-of-visual-words (BoVW) to tackle this problem, but not all SALM systems require hand-crafted feature. With the improvement of machine learning, Convolution Neural Networks (CNNs) has a significant effect on feature detection. This paper proposes a loop closure detection method without hand-crafted feature. We extract the image features through CNNs, and reduce the dimensions of the feature values with t-distributed stochastic neighbor embedding (T-SNE). And then we get a dictionary of two-dimensional feature points, which are obtained by T-SNE. Combined with the new similarity judgment method, the BoVW model based on CNNs is constructed. The new method can solve the loop closure detection of SLAM systems without hand-crafted features. Based on the characteristics of CNNs, the performance of scale-invariant feature transform has been significantly improved.","PeriodicalId":254705,"journal":{"name":"2019 Chinese Control And Decision Conference (CCDC)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132004476","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}
