| Abstract: | This paper points out that the traditional compatibility check method for flight test data, developed early in 1970's and thereafter be used widely,has some disadvantages and limitations, and gives a new method-three-step method,which overcomes the drawbacks existed in traditional method and makes the whole procedure very simple. At the same time,an algorithm to make the estimated parameters controllable is presented to improve the robustness of parameter estimation. Numerical stable Carlson Square-Root decomposition filter is used to estimate the state and parameters simultaniously. Calculation example indicates that the new three-step method and the algorithm te improve robustness of estimated parameters is valid,especially suited for processing measured flight test data. |
