ABSTRACT The IDIM (Inverse Dynamic Identification Models) method is based on a closed loop identification of the inverse model which is linear in relation to the parameters. By mixing the OE (Output Error) method and the IDIM technique, we obtain the method called DIDIM (Direct and Inverse Dynamic Identification Models). Experimental results on decoupled identification of the electrical dynamic and the mechanical dynamic have proven the efficiency of the IDIM and the DIDIM methods. But to perform a global identification of all the parameters, whatever the electrical machines (direct current motor, synchronous motor, asynchronous motor), it has been necessary to introduce two phases of calculations to get the parameters. This is why we have called them IDIM2 and DIDIM2. In this paper, we have presented the comparison of these four methods with experimentations on a DC motor, which has simple equations, to see easily nuances between IDIM, DIDIM, IDIM2, DIDIM2.

使用基于 IDIM、DIDIM、IDIM2、DIDIM2 的方法识别电动执行器的参数

摘要 IDIM（逆动态识别模型）方法基于与参数呈线性关系的逆模型的闭环识别。通过混合 OE（输出误差）方法和 IDIM 技术，我们获得了称为 DIDIM（直接和反向动态识别模型）的方法。电动力学和机械动力学解耦识别的实验结果证明了 IDIM 和 DIDIM 方法的效率。但是要对所有参数进行全局识别，无论是何种电机（直流电机、同步电机、异步电机），都需要引入两个计算阶段来获取参数。这就是我们称它们为 IDIM2 和 DIDIM2 的原因。在本文中，
