Embodiment Construction
[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings.
[0023] A fault diagnosis system for the hydraulic steering system of a self-propelled hydraulic truck of the present invention, the fault diagnosis system is based on the ARX model and FCM clustering, and is obtained by programming in C++ language, and the fault diagnosis system is stored in the hydraulic steering system Each controller (such as figure 2 shown). The ARX model is an auto-regressivewithextrainputsmodel, referred to as the ARX model. The FCM clustering is fuzzy C-means clustering, fuzzyC-means, FCM clustering for short. In the present invention, please refer to "Fault Diagnosis of Excavator Hydraulic System Based on Derived Regression Model and Fuzzy C-means Clustering" published by He Xiangyu and He Qinghua for the definition of ARX and FCM models, Journal of Jilin University (Engineering Edition), 2008, 38(1): 13-187. The amount of inform...
