Firstly,different control strategies for sensor management are modeled by the real language measure. The legal behavior of control strategy modeled by FSA can generate a partially ordered set of controlled languages. Then an identification method of the language measure parameters based on an FSA model is proposed. The language measure creates a total ordering on the performance of the controlled languages.
