Embodiment Construction
[0050] The present invention will be described in detail below in conjunction with the accompanying drawings and specific implementation examples.
[0051] The invention discloses an industrial process fault detection method based on a supervised linear dynamic system model. The method aims at the fault detection problem of the industrial process. Firstly, a distributed control system is used to collect process variable data and quality variable data, and standardize them deal with. Then a supervised linear dynamic system model is established, and the model parameters are stored in the database for future use. Finally build T for the new online data 2 Statistics, compared with statistical limits to obtain fault detection results.
[0052] The main steps of the technical solution adopted in the present invention are as follows:
[0053] The first step: use the collection and distribution system to collect data of process variables to form a training sample set of process var...
