Intelligent Arithmetic for the State Evaluation Feature Selection and Optimize

Feature selection is the basic of the state evaluation and fault diagnosis, and it is difficult to get the reasonable token feature. In the paper, an intelligence method of state feature system establishment and optimize has been studied. Diesel engine was illustrated in the paper, the signal of diesel engine has been collected when the piston ring and airtight ring working at different state, then with the intelligent algorithm, an optimum parameter combination has been received. Example shows this intelligent feature selection and optimize method is sample and efficiency, furthermore, this method is valuable for the virtual state evaluation of similar complex system.
