摘要 研究受滑动平均有色噪声干扰的非均匀采样非线性系统的参数辨识算法.针对系统中存在不可测中间变量的问题,利用辅助模型对其进行估计,进一步提出递推增广最小二乘算法对系统参数进行辨识.并通过计算机MATLAB仿真验证了算法的有效性. Based on the auxiliary model method, the least square recursive algorithm is derived for the nonlinearoutput error moving average system. In summary, this paper studies and derives the identification algorithms fornonlinear system with multirate sampling, and the effectiveness of the algorithms is illustrated by Matlab simulations.
