摘要
应用积矩矩阵辨识系统的阶次,分析了系统的可辨识性。在输出端带有色噪声干扰情况下,运用扩充最小二乘法构造了观测矩阵,并进行了参数估计。辩识结果表明:该方法辩识精度高。
The order of model can be estimated by accumulating matrix, and the identifiability of system was analyzed. For the noise conditions of colored noise in output, an extended least square method was presented. The constitution of the observation matrix was introduced. The identification results illustrate the quite accuracy of the method.
