摘　　要：为规避真实对象的建模过程,使辨识对象的建模与内模控制器设计可同步实现,将虚拟参考反馈校正思想应用于内模控制之中。虚拟参考反馈校正思想可将辨识对象和内模控制器的求解转化为参数辨识过程。为建立虚拟参考反馈校正思想与传统自适应控制方法间的等价性,推导出对输入-输出观测数据作预滤波处理的滤波器。最后用仿真算例验证本文辨识方法的有效性。To avoid the process of identifying the true plant, the idea of virtual reference feedback was applied for tuning into the internal model control in order to identify the identified model and internal model controller sim- ultaneously. The idea of virtual reference feedback tuning can formulate the problem of how to identify the identified model and internal model controller into a process of identifying two classes of unknown parameter vectors. To estab- lish the equivalence between the virtual reference feedback tuning and the classical adaptive control, the filter which is used to filter the input-output observed data is derived. Finally, the efficiency of the proposed identification strate- gy can be confirmed by the simulation example results.
