摘要:
针对传统参数辨识方法计算复杂且依赖过多测试数据的问题,提出一种基于尺度变换的直流电机参数辨识新方法.首先,建立具有驱动放大系数和响应时延的电机系统与一类标准化对象之间的频域/时域尺度变换关系.然后,分析标准化对象的阶跃响应特征与主导参数的作用,结合主导参数定义,拟合反映阶跃响应特征的函数.最后,基于尺度变换与特征函数,给出电机模型参数的直接计算方法和优化计算方法.仿真和实验结果表明:文中所提方法具有正确性和有效性.
Abstract:
In view of the problem that the traditional parameter identification method is complicated in calculation and relies on too much test data, a new identification method for direct current motor based on scaling transformation is developed. Firstly, scaling transformation in time and frequency domains between the motor system and a class of normalized model is developed with drive amplifying and response delay considered. Secondly, the step response characteristic of the normalized model and the role of the dominant parameters are analyzed, and the characteristic function are defined and fitted by employing the dominant parameter. Finally, based on the scaling transformation and the eigenfunction, the directly calculation scheme and optimal searching scheme of the model parameters are given. The simulation and experimental results proved the validity and practicability of the proposed methods.
