在联合输入/输出辨识方案中，随机实现被用来解决谱分解问题，从而提供了一种时域闭环辨识方法。首先，得到了联合闭环系统的随机实现。通过状态空间划分，可以计算子进程的非最小实现。然后，平衡缩减提供了循环中子过程的最小实现。仿真实例表明，该方法具有良好的效果. <<ETX>>
Within the joint input/output identification scheme, stochastic realization is used to solve the spectral factorization problem, thus providing a time-domain closed-loop identification method. First, a stochastic realization of the joint closed-loop system is obtained. Through state space partitioning, nonminimal realizations of the subprocesses can be calculated. Balancing reduction then provides minimal realizations of the subprocesses in the loop. Simulation examples show good results with the proposed method.<<ETX>>
