On the basis of direct modelling method by using extended Kalman filter, a new method combining extended Kalman filter with adaptive extended Kalman filter is presented to model gyro drift directly from rotate angle of turntable. Extended Kalman filter has great estimation error, what is more, may be divergent if the model and noise statistic are not accurate or wrong. The new method solves the problem of general extended Kalman filter by using fictious noise with timevarying statistic to compensate the linearized model error of extended Kalman filter. The parameter estimators of single-axis and double-axis servo test are designed from it.

In the experimental research, the levitation force of a HTS above a permanent magnetic guideway was first investigated in the case of zero-field cooling. The hysteresis of the levitation force curve and the interaction between a HTS and the applied magnetic field were explained by the Bean model, and the effect of the measuring precess on the levitation force was further analyzed.
