摘要
由于考虑系统的安全性和经济性无法进行开环实验,而目前最常用的闭环继电反馈辨识方法需要进行数次的继电反馈实验,并且该方法只能辨识固定结构的低阶模型,无法满足实际工业的需要。针对这一情况,提出了一种新的含积分环节过程对象的频域模型辨识方法,其能快速找到对象模型的主要频率段,分析频率段内的频率特性,从而准确地辨识出含积分环节对象的模型。仿真实验的结果表明,该辨识方法能够高效且准确地辨识出含积分加环节的对象。
The open loop experiment can’t be done because of systems’ security and economy.Also the close-loop identification method which is mostly commonly used to identify the object is by using relay feedback,due to this method needs several relay feedback tests and only for fixed structure low order models,so it can’t meet the actual industrial requirements.According to this circumstance,this paper raised a new technique of modeling identification for process with integral unit model. It could find a main frequency band of the object quickly and analyzed frequency response.Then the model with integral unit could be identified accurately.The results of simulation show that this method can acquire a great identification effect.
