本文推导了双速率系统的数学模型,提出了一种估计模型参数的随机梯度辨识算法和一种直接根据双速率输入输出数据计算样本间输出的输出估计算法。此外,我们研究了参数估计和样本间估计的收敛性质,并用实例系统(包括一个实验水位系统)对所提出的算法进行了检验。
In this paper, we derive a mathematical model for dual-rate systems and present a stochastic gradient identification algorithm to estimate the model parameters and an output estimation algorithm to compute the intersample outputs based on the dual-rate input-output data directly. Moreover, we investigate convergence properties of the parameter and intersample estimation, and we test the proposed algorithms with example systems, including an experimental water-level system.
