| 摘 要： | 传统的闭环系统可辨识性受到外部激励和控制器结构的限制,然而在实际辨识应用中,由于过程操作条件的限制或者经济原因不希望存在外部持续激励。讨论了在无外部激励下基于快采样的多变量子空间模型闭环可辨识性,提出了无外部持续激励条件下的闭环快采样子空间模型辨识方法,在常规采样的可辨识性条件不满足或部分满足的情况下,通过对闭环系统控制对象的输入输出变量快采样来实现对象模型辨识,并通过仿真实例验证了基于快采样的辨识算法的有效性。

| Abstract: | The identifiability of traditional closed-loop system is restricted by external excitation and controller's structure.However in actual identifying applications,it is undesired to have consecutive excitation due to process operation conditions or economic limits.In this paper we discuss the identifiability of closed-loop without external excitation for fast-sampling-based multi-variable subspace model and propose a new identification method for closed-loop fast-sampling subspace model in condition of withou... |
