Although the formation control of multiple spacecraft has been widely studied from various aspects, the problem is still not well resolved, especially when facing sensor failure in some spacecraft. This paper presents an integrated design method for distributed observers and controllers to realize formation control of multiple spacecraft in the presence of sensor failures. By viewing the group of spacecraft as an entire system and utilizing the sensor measurement of other spacecraft, the distributed observer to estimate the entire system is designed for each spacecraft based on the controller prediction of all spacecraft, and meanwhile the local controller is proposed based on the distributed observer. Theoretical analysis and simulation result show the effectiveness of the proposed integrated method. © 2024 IEEE.

Optics in high-power solid-state laser devices will be damaged and adhere to contaminates on the surface during manufacturing and operation, which reduces the service life. To facilitate the positioning and recognition of the flaw (damage and contaminates) in the process of automatic repair, the dark-field flaw size calibration algorithm was studied. In this paper, a flaw size calibration model based on convolutional neural network was established. The size, exposure time, and loss function of damage and contaminate were optimized respectively. The training parameter of the damage regression model is determined to be size of less than 500μm, 30ms of exposure time and SmoothL1 loss function, and the parameter of contaminate is 0-100μm, 20ms of exposure and SmoothL1 loss function. After data balancing, the calibration precision was improved. To improve the calibration consistency of the full-size segment, a comprehensive size calibration strategy is proposed. The CNN regression algorithm is used for small size, and the pixel-level calibration algorithm is used for large size. Compared with the single regression calibration algorithm, the relative error and absolute error of the calibration results of small damage ( © 2024 SPIE.

The remaining useful life (RUL) of lithium-ion batteries, a pivotal metric for assessing battery performance and service life, is not amenable to direct measurement. To refine the precision of estimating the remaining useful lifespan for battery systems, this paper proposes a prediction method based on the Bayesian optimization algorithm for Long Short-Term Memory (LSTM) and Gated Recurrent Unit (GRU) neural networks. The research utilized the battery dataset provided by the MIT Stanford Toyota Research institute. The method first preprocesses the battery data, selecting key health indicators (HI) through the Pearson correlation coefficient, and then estimates the RUL of the battery using LSTM and GRU networks. In order to augment the efficacy of the RUL estimation model, this paper applies Bayesian optimization technology to determine the optimal hyperparameters, thereby saving time required for model prediction. © 2024 IEEE.
