We consider several important issues concerned with designing a closed loop system for an unknown plant based on input/output measurements. The main results are as follows.1. We have proposed a direct method to obtain parameters of the desired controller via controller identification from the input/output measurements and the desired response instead of model identification of the plant. The proposed method is an extension of the existing method, i.e., VRFT and FRIT. A salient feature of the proposed method is to be able to detect unexpected closed loop instability by using identification error.2. We addressed the issues on the optimality of the parameter obtained FRIT, and have provided the theoretical result that applying a prefilter enables us to obtain the actual optimal parameter for the achievement of the optimal tracking performance. Based on this theoretical result, we have also expanded FRIT into more practical method in the sense that the optimization can be performed in the linear computation, which implies that the result obtained here can be examined by more simple computation.3. We have proposed a new concept "identification of a plant via controller identification" of system identification based on controller tuning. That is, by tuning a controller including the structure of a plant, we have an optimal parameter of the plant reflecting the information of the data and the given specification.4. We have addressed the connection between an existing canonical controller and proposed FRIT. We have reformulated canonical controllers in our framework. As a result, we have refined FRIT in the sense that the tuning method done in FRIT yields the parameter fitting the data and the given specification from the theoretical points of view.5. We have extended the proposed method to obtain a single controller which uniformly achieves control performance under plant dynamics variation.

我们考虑了基于输入/输出测量值的未知工厂设计闭环系统的一些重要问题。主要结果如下1。我们提出了一种直接方法，通过从输入/输出测量值和所需响应而不是植物的模型识别来获得所需控制器的参数。提出的方法是现有方法的扩展，即VRFT和FRIT。所提出方法的显着特征是能够通过使用识别错误检测出意外的闭环不稳定性2。我们解决了有关获得的参数的最佳性问题的问题，并提供了理论上的结果，即应用预滤器使我们能够获得实现最佳跟踪性能的实际最佳参数。基于这个理论结果，我们还将弗里特扩展为更实际的方法，因为可以在线性计算中进行优化，这意味着可以通过更简单的计算来检查此处获得的结果。3。我们提出了一个基于控制器调整的系统识别的新概念“通过控制器识别植物的识别”。也就是说，通过调整包括工厂结构在内的控制器，我们具有反映数据信息和给定规范的最佳参数。4。我们已经解决了现有的规范控制器与提议的FRIT之间的联系。我们在框架中重新重新制定了规范控制器。结果，我们从理论观点的观点中得出拟合数据的参数和给定规范的参数，从而使弗里特进行了完善。5。我们扩展了提出的方法，以获取单个控制器，该控制器在植物动力学变化下均匀地实现控制性能。
