Truncated D-optimal design of accelerometerexperiments on centrifuge
Beijing(2009)
Abstract
In order to calibrate the high-order coefficients and to increase the experimental accuracy of accelerometers tested on centrifuge, the D-optimal theory is applied in the experimental optimal design. Due to that the low-order items of accelerometers are inaccurate in the test on centrifuge, the truncated D-optimal algorithm is presented to solve this problem. The iterative computational algorithm is repeated until the maximal dispersion points of model equations are achieved. The experimental results demonstrate that the proposed method used in model identification of high-order parameters outperforms general D-optimal design methods.
