摘　　要：利用强跟踪滤波理论实现了一类单变量时变过程的时变时延和模型参数的联合实时估计,并将其用于控制过程方差性能的评估.结合性能评估的FCOR策略,给出了适于单变量变时延过程方差性能评估的VFCOR算法.仿真示例说明了该方法的有效性.By the strong-tracking filtering theory, the on-line joint estimation of time delay and model parameters is realized for a class of single-input single-output（SISO） time-varying processes with varying time-delay. Then, combining with the FCOR（filtering and correlation） strategy, the joint estimation method is applied to assess the output variance of the controlled process. The VFCOR（varying time-delay FCOR） algorithm is developed for such kind of processes. Simulation examples are performed to validate the proposed strategy.
