针对输入非线性系统存在两个未知参数集乘积项,导致模型参数不可辨识的情况,采用规范化系统参数方法来分离关键变量,提出了最小二乘迭代参数估计算法,来辨识输入非线性受控自回归系统的参数.仿真结果验证了其有效性.
Aiming at the fact that there are two product items of unknown parameters in the input nonlinear system, the model parameters are indistinct, and the key variables are separated by the standardized system parameter method. The least square iterative parameter estimation algorithm is proposed to identify the input nonlinear controlled The parameters of regression system are validated by simulation results.
