Research on Modeling of Stabilized Aim Control System Based on dSPACE

In order to improve the analysis and design capability for airborne stabilized aim servo control system,a modeling method based on dSPACE was introduced.The active signal was sent to the object system and the response signal was acquired by using dSPACE.The system's frequency characteristic was obtained by least square methods and the transfer function was fit by using Ident toolbox in MATLAB.This method was used in the controller design for an airborne stabilized aim servo system,and the validity and practicability were proved by the experiment results.
