Research progress of data-driven methods in fault diagnosis of chemical process

The data-driven method is a black-box model, which has the advantage of autonomously mining and constructing the internal relationship of data. The development of perception equipment and the improvement of computing power highlight the advantages of the data-driven method, which can better independently mine and build the internal relationship of data. This paper introduces the principles and functions of various data-driven methods, analyzes the advantages and disadvantages of the methods and the practical application direction, and draws the conclusion that deep learning and integrated learning are the key research points of data-driven methods in the future. This paper reviews the research and application of data-driven methods for fault diagnosis in chemical processes in the recent five years, and finally comprehensively analyzes the current research situation in this field. The analysis shows that it is effective to solve problems in chemical processes by combining multiple data-driven methods. Furthermore, the research direction of data anomaly and time lag is provided. In this paper, it suggested that the mechanism of the method should be studied and optimized. In the future, the development and research of data-driven methods for fault diagnosis in chemical processes should focus on two points, namely “practicality” and “timeliness”.
