In view of the characteristics of dense and non-stationary outliers in remote sensing data of navigation satellite in complex space environment, a method of eliminating outliers in residual test based on time-varying radial basis neural network was proposed. In the method of outliers elimination, the time-varying radial basis neural network (RBF) is firstly modeled according to the telemetry data. After the training network is stable, the residuals of the original sequence and the fitting sequence based on RBF neural network are calculated. Then the residual is tested by the adaptive threshold value to determine the outliers in the telemetry data. Finally, the method is proved to be effective in detecting isolated outliers and speckled outliers by practical application.

Many intelligent methods have been proposed and applied in the field of autonomous manufacturing inspection. These advanced algorithms with high requirements on computing power and network may lead to time delay, high cost and energy consumption in practical applications with massive data to be processed. We carry out an efficient defect detection system in an end-edge-cloud architecture with the concept of edge computing to process the big data quickly and effectively. A branchy deep learning model with early exit capability of inference is proposed to detect the category and location of the defect in printed circuit boards. We offload part of the computing tasks to the edge nodes by segmenting and deploying the DL model. Therefore, our system has high detection efficiency and makes real-time defect detection possible.

In this paper, an online adaptive dynamic programming (ADP) scheme that combines eligibility trace is presented for solving optimal control of discrete-time systems. In contrast with the forward view learning that requires to store additional vectors to update, the backward view learning of the proposed scheme employs online collected data and previous gradient information to update the neural network (NN) parameters at each step, which reduces the computational burden. In order to approximate the cost function more accurately to achieve a better policy improvement direction in the exploration process, the proposed algorithm introduces an independent costate network on the basis of the traditional HDP framework to approximate the costate function. By utilizing the costate as supplement information to estimate the cost function, the estimation accuracy has been greatly improved. Finally, two numerical examples are presented and the simulation results demonstrate the effectiveness and the advantage of computation efficiency of the presented method.

In order to solve the problem of insufficient data in the process of constructing concentration monitoring model of ammonia nitrogen in intensive aquaculture, a new improved data generation model of TableGAN is proposed based on the model optimization algorithm. The method generates synthetic data with the same distribution characteristics as the original data by confrontation training, and makes the generated data more effective in the optimization model by adding classifiers and optimization functions. The field data of a breeding enterprise show that the accuracy of the ammonia nitrogen concentration soft sensing model trained by the synthetic data set is better than that of the model trained by the original data set in terms of root mean square error and maximum absolute error, and the test effect of the model is also improved significantly.

The data collected by various sensors in monitoring the operating status of aero-engines can be used to predict the Remaining Useful Life (RUL) of aero-engines. 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.

This paper proposes a novel integral sliding mode robust control method for tracking control of robot manipulators based on Hamilton-Jacobi Inequality theory and a nonlinear disturbance observer. 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.

China's independently developed Beidou 3 system has been fully operational and has achieved global positioning. In order to further improve the satellite navigation and positioning function of the ground mobile robot terminal, the influence of the high-frequency oscillating random disturbance signal received by the mobile robot data and the high-order nonlinear dynamics of the system on the navigation and positioning accuracy was analyzed, and the time-varying characteristics of the dynamic adaptive RTK-GPS positioning algorithm were used. 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. Experimental results show that this method is still suitable to improve the positioning accuracy in non-stationary environment, enhances the acquisition and tracking characteristics of the system, especially when the observation satellite is maneuvering, and the error of positioning results can be significantly reduced.
