| 摘 要： | 为解决直流电动机实际运行中模型参数因受到运行环境、工况等条件的影响而导致其建模不精确的问题,研究和比较了递推最小二乘法、指数遗忘的递推最小二乘法、矩阵规范化的递推最小二乘法、投影算法、正则化的最小二乘法5种实时参数估计方法。引入平方误差积分准则、时间平方误差积分准则、绝对误差积分准则和时间绝对误差积分准则,对实时参数估计的精度和效果进行评判。计算机仿真结果表明,对于时变的直流电动机模型参数,RLSEF算法具有在误差积分准则意义下的最优辨识精度。

| Abstract: | The parameters of a direct current motor model are often influenced by operation environments or working conditions and are imprecise.To solve this problem,this paper studies and compares the performances of five methods: Recursive Least Squares(RLS),Recursive Least Squares with Exponential Forgetting(RLSEF),Recursive Least Squares with Matrix Regularization(RLSMR),Projection Algorithm(PA) and Normalized Least Mean Square(NLMS).Four error integration criteria(ISE,ITSE,IAE,ITAE) are used to test and evaluate... |
