An Improved FCM Algorithm Based on the Firework Algorithm for Liquid Rocket Engine Fault Detection

A novel fault detection method based on fuzzy C-means (FCM) clustering algorithm is proposed for a liquid engine of a launching rocket. However, the FCM algorithm is sensitive to the initial cluster center, and the search process suffers from local optimums. Therefore, this paper proposes an improved FCM based on the firework algorithm. The improved FCM utilizes the explosion and mutation mechanism of the firework algorithm to initialize the number of cluster center for FCM iteration, which makes up for the deficiency of the FCM clustering algorithm. Finally, the effectiveness and validation of the algorithm are verified by simulation.
