Abstract
A method of establishing linear system model based on rough set theory is studied in this paper to deal with the control of the linear system. Firstly, the decision table is acquired based on the input-output sampling data of the linear system, then discretized. Secondly, the decision rule is obtained according to the importance of attributes on the basis of the relative reduction. Then, the rough set model of the linear system is attained. The present study takes a practical linear system as an example, and then constructs its rough set model. The simulation result reveals the validity of the model.
