结构适应式自校正预报器和调节器

STRUCTURE-ADAPTIVE SELF-TUNER AND ITS APPLICATION

对一类时变结构系统给出两种变法构递推算法。在此基础上,本文对非线性系统提出一种结构适应式自校正递推预报器,对线性系统提出一种结构适应式自校正调节器。实际应用表明,上述算法能自动跟踪系统结构性变化。这使得带上述算法的自校正器能很好地适应系统结构性变化,从而大大改善变结构系统预报和控制的精度。

In this paper, two variable-structure recursive algorithms are given to a kind of time-varying structure systems. Based on this, we put for- ward a structure-adaptive self-tuning recursive predictor to nonlinear sys- tems, and structure-adaptive self-tuning regulator to linear systems. In practical application, the above algorithms can change the model structure automatically when the system structure varies. This makes the self- tuner with the above algorithms adapt to the change of the system struc- ture, and the prediction and control accuracy can thus be improved.
