Firstly, the dynamic model of the manipulator considering the uncertainty and external disturbance is established through the Lagrange method. Secondly, a nonlinear disturbance observer is designed to estimate and compensate the composite interference. Hamilton-Jacobi Inequality theory and the designed disturbance observer are then applied to design the integral sliding mode robust control law with a new integral sliding mode surface. Finally, the proposed controller is employed for tracking control of a two-degree-of-freedom manipulator and compared with the conventional sliding mode controller. The comparison results demonstrate that the proposed approach can provide superior performance such as high tracking accuracy, fast transient response, and low chattering.","PeriodicalId":106675,"journal":{"name":"2021 3rd International Conference on Industrial Artificial Intelligence (IAI)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121537914","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 dataset has characterisitcs of high dimensions and large scale, which increase the difficulty of accurately predicting RUL. To obtain more accurate prediction results, this paper proposes a prediction model based on dynamic ensemble learning to predict RUL of aero-engines. The model selects the K nearest neighbor samples of one testing sample, dynamically determines the weight of each learner by evaluating the local performance of this learner in the neighbor samples, and constructs a weighted kernel density estimation function based on previously calculated weights to achieve integrated prediction of multiple base learners dynamically. In order to better determine the similarity between the data, an improved adaptive KNN (K-Nearest Neighbor) algorithm is introduced, and the importance of each sensor is introduced into the traditional distance measurement, and the adaptive K value selection is realized through the relationship between the global average density and the local density. In order to reflect the short-term and long-term dependencies between samples in dataset better, neural network LSTM (Long Short-Term Memory) is selected as the base learner of the dynamic ensemble learning model. Finally, the aircraft engine simulation data set C-MAPSS released by NASA is used for simulation verification. The experimental results show that the model proposed in this paper can improve the forecast precision of aero-engines’ RUL.","PeriodicalId":106675,"journal":{"name":"2021 3rd International Conference on Industrial Artificial Intelligence (IAI)","volume":"97 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126060836","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}

A process neural network (PNN) based on empirical pattern decomposition (EMD) is proposed. Firstly, the existing input signal of the satellite positioning terminal is decomposed into several intrinsic mode functions (IMFs) using the EMD method. Then, for each IMF, the neural network model is constructed, and the dynamic error data is used as the sample for the neural network model correction training. For the satellite signal interference or lock loss process, the trained neural network is used to predict the output divergence to suppress the position and speed errors, so as to improve the accuracy of positioning and navigation.
