| Abstract: | The Kalman smoothing is,for the first time,employed to the measurements of dynamic thrust for Solid Rocket Motor(SRM).This method is entirely a new practical method with high precision for the dynamic measurement.First,the dynamic model about the thrust is achieved according to the SRM theory,a survey is also made for adaptive estimation of noise variances,the determination of the initial parameters and the estimator performance.Then,the computer simulation is carried out,and the actual application is implemented.The results are satisfactory and indicate that the application of Kalman smoothing to the dynamic thrust measurement is successful. |
