| 摘 要： | 对自感知的两种实现方法：电桥电路解耦与观测器解耦法，分别进行仿真并对观测器法进行实验验证。电桥电路仿真加入非线性模型，并对桥路输出信号进行放大滤波，为实验提供理论依据。观测器通过实验与观测计算对比验证了基于观测器自感知的可行性。

| Abstract: | Two implementation methods for self-sensing, the bridge circuit method and the observer method for giant magnetostrictive self-sensing actuator were simulated respectively and the observer method was verified through experiments. The non-linear model was built up in the bridge circuit, while the amplifier and filter circuit were designed in the simulation which provided the theory for the experiment. The validity of the observer is proved by the comparison of the calculated result and the experimental result. |
