摘要 分析了超磁致伸缩材料(GMM)自感知的机理。在对GMA建模的基础上,提出了利用最小二乘法对电路模型进行参数辨识的方法,间接获得电感L的值,利用基于线性叠加磁致算子的解偶算法,从而实现感知外载力F和位移S。 The mechanism of self-sensing in Giant magnetostrictive material (GMM) was analysised in this paper.Based on the modeling of GMA, the parameter identification method using least squares on the circuit model was proposed,which was access to get the value of inductance L indirectly,and the force F and displancement S can be perceived using a linear superposition of scalar hysteresis operators.
