To date, bipolar membrane electrodialysis (BMED) is being developed as a competitive technology for waste lithium‐ion battery recovery. However, the purity and concentration of lithium hydroxide generated from a BMED plant could not meet the product criteria for ternary lithium batteries, thus requiring additional condensation, purification, evaporation, and crystallization procedures. Herein, bipolar...
As one of the most critical issues for target track, α-Jerk model is an effective maneuvering target track model. Colored noise always exists in the measurement process of the tracking target system which usually influences the tracking performance. A novel maneuvering target track approach based on an unscented particle filter is derived. The unscented particle filter (UPF), which uses the unscented...
All-time and autonomous satellite navigation plays very important roles in the space technology application. In this paper, a state filter and prediction algorithm combined with a cubature Kalman filter (CKF) and a numerical integration method is proposed to realize the all-time and autonomous navigation for the satellite system. The navigation system takes the satellite's on-orbit dynamics model...
Current industrial system develops more and more complex and intelligent, whose safety and reliability relies on fault diagnosis technology. In the age of big-data, data-driven fault diagnosis becomes the state of the art, and the demand for the diagnostic toolbox also increases. In this paper, theories of data-driven fault detection models, both static model and dynamic, are revealed. And then a...
Data fusion for parameter estimation with multi-structure and unequal-precision is considered in this paper. Matrix tools e.g., congruent transformation, trace function and matrix differential, are used to analyze the estimation performance. Theoretical results reveal that: the single equipment estimate, the optimal fusion estimate, and the joint estimate are some special cases of the fusion estimate...
In this paper, a fault diagnosis method is proposed based on component-wise expectation maximization algorithm and k-means algorithm, and it is applied to diagnosing the fault of the satellite attitude determination control system. First, Gaussian mixture model and the its traditional parameter estimation algorithm are reviewed. The component-wise expectation-maximization algorithm is used to estimate...
The state and the fault prediction for the measure & control equipment in the test range plays an important role in the test and evaluation for the large-scale weapon system. It is also a research development in the state or fault process region. The objective of this paper is to address a state or fault prediction method for the equipment in the test range, which is combined with the physical...
