| 摘 要： | 本文针对计算机采样控制系统,提出了一种过程模型参数的闭环辨识方法,并直接在离散域中推导出其辨识估计算法,由于设计控制器所用的对象参数估计值的不准确,将使系统的实际输出与期望输出之间产生偏差,利用该偏差,本方法实现了对象参数的闭环辨识。

| Abstract: | In view of computer sampling control systems , a parameter closed-loop identification method for process model has been presented in this paper and its identifying algorithm is derived directly in discrete-time domain. The controller involves the reduced model and the initial estimated parameters of the process, so the difference between the actual and expectant system outputs results from the inaccuracy of the initial estimated parameters of the process in pratical control. Then the differences are used to realize the closed-loop identification of the actual parameters of the process in this method. |
