提出了一种仅利用输出互采样方法获得的被控对象输入/输出数据的直接闭环辨识方法。通过采用比控制间隔更快的系统输出采样，我们可以澄清，间采样的对象模型也可以由SIMO模型结构描述，这可以提供闭环的可辨识性。该辨识方法的优点之一是利用互采样输出观测值可以消除通常的可辨识性限制条件，并且不要求参考输入具有持续激励特性。其有效性是通过使用磁悬浮系统的实验研究证明。
A new direct closed-loop identification method only using the plant input/output data acquired through an output inter-sampling scheme is presented. By taking the faster sampling of the system output than the control interval, we can clarify that the inter-sampled plant model can also be described by a SIMO model structure, which can provide the identifiability of the closed-loop. One of the advantages is that the proposed identification method using the inter-sampled output observations can remove the ordinary restrictive identifiability condition, and it is not required that the reference input holds the persistently exciting property. Its effectiveness is demonstrated through an experimental study using a magnetic suspension system.
