辨识模型与遗忘因子法所用模型相同，其中， 0 ≤μ≤1为遗忘因子， 此处取0.98。 数据长度L=402。一次算法和递推算法结果基本一致，但递推算法可以实现在线实时辨识，而且可以减少计算量和存储量。-Identification model and forgetting factor method used the same model, among them, 0 or less or less 1 μ for forgetting factor, here take 0.98. Data length L = 402. A algorithm and recursion algorithm results are basically the same, but the recursion algorithm can realize the real-time online identification, and can reduce the computation time and memory requirement greatly.
