粗糙集神經(jīng)網(wǎng)絡(luò)在注水泵機組故障診斷中的研究
[Abstract]:At present, computer intelligence has been widely used in fault diagnosis. Rough set theory is proposed by Professor Z.Pawlak of Poland. It is a mathematical tool for studying the expression, learning and induction of inaccurate knowledge and incomplete data. Artificial neural network is a nonlinear dynamic system that simulates human thinking, and has parallel cooperative processing. Learning ability can realize recognition and classification, optimization calculation, associative memory, knowledge processing and other functions.
The vibration data of the water injection pump unit contain a lot of information of the working state of the water injection pump unit. It is an important data for the fault diagnosis of the water injection pump unit. This paper uses the attribute reduction of the rough set, the knowledge processing and the learning, classification and parallel processing ability of the neural network, and establishes a rough set neural network to complete the fault diagnosis of the water injection pump unit.
In this paper, the research results of rough set and neural network are combined to reduce the dimension of sample features effectively by rough set theory, and then use the reduced sample to construct network to reduce the time of learning and operation of neural network. Finally, the fault diagnosis system of water pump unit is built by using MATLAB software.
The results of network diagnosis show that the simulation results coincide with the actual sample knowledge, which shows that the network can correctly diagnose the fault. The research of rough set neural network in the fault diagnosis of water injection pump unit has certain theoretical significance and practical value.
