| Abstract: | This paper was mainly about dynamic model real*.time parameter estimation of control system equipment in missile based on measuring data, a recursive Fourier transformation was used for real*.time data analysis. A method for real-time parameter estimation based on linear dynamic state space model was developed. The application demonstrates that this method can produce accurate model parameter with appropriate error bounds, and has good performance in convergence. This real*.time parameter estimation method has low computational requirements. |
