摘要：
An equation system for the anhysteretic curve and the distribution function required by a hysteresis model is suggested. A least-square fitting confirms that the solution is unique and gives optimal agreement with the measurements. Moreover, the used fitting function with three parameters replaces the measured vector, which increases simulation performance. (C) 2003 Elsevier B.V. All rights reserved.
