| 中文摘要 |
| 运用特征分析和“类等效”建模的方法, 把直流电机双闭环调速系统的模型, 简化成一个简单的具有非线性特性的状态空间模型. 进而提出了通过实测系统的转速响应, 利用改进的遗传算法对该模型参数进行精确辨识的方法. 为检验方法的有效性, 对该模型和常用模型进行了对比性验证实验. 实验结果表明由此建模和参数辨识方法建立的模型结构合理, 参数辨识精度高, 可以很好的替代实际调速系统进行系统的设计. |
| 英文摘要 |
| Using the method of characteristic analysis and “quasi-equivalent”modeling, we reduce the model of the double loop DC motor control system to a simple non-linear state space model, and then, apply the improved genetic algorithm to accurately identify the model parameters, based on the real rotational speed response. This method is validated by comparing the reduced model with other conventional models. Experimental results show that the proposed method has a reasonable structure with parameters to be identified accurately. It is applicable to the design of the real DLM control systems. |
