The Levy method was introduced into the modeling of missile's pneumatic actuator, and the mathematical model of the actuator was identified using the frequency characteristic data deriving from test. Through comparison between the results of control system simulation in Matlab and the tested data, it was shown that the error of the model built was small and had higher fitting precision in the frequency band from 1Hz to 30Hz, which met the requirements of general design for missile. A relatively accurate pneumatic actuator model was provided for guidance control system of missile.
