In the industrial control system

there are many researches on performance evaluation with single running data

and less on multi-attribute performance evaluation. Against the requirement of main steam temperature control system in production process of thermal power plants

a multi-attribute performance evaluation method for the main steam temperature control system of thermal power units based on the single-valued neutrosophic set is proposed. Firstly

the neutrosophic set decision matrix is established based on multiple attribute values of the operating data of the main steam temperature control system of thermal power units. Then

on the basis of the information provided by each attribute

a single-valued neutrosophic set decision matrix that reflects the opinions of the decision maker is determined

and all the individual decision matrixes are aggregated into a common decision matrix by a weighted average operator. Finally

each control scheme is evaluated based on the degree of the relative closeness function which is calculated based on the Euclidean distance between the calculated control plan and the positive and negative ideal solutions of the neutrosophic set

and the optimal control plan is determined. The simulation results show that the proposed method is effective and reasonable

and the calculation is simple.
