摘要
本文给出一种变结构式推广的递推梯度算法和一类非线性系统结构适应式预报器。这种算法能够自动改变模型的结构。通过油田预报实践,表明这种预报器能跟踪系统结构性变化,从而提高变结构系统的预报精度。
<ABSTRACT> A recursive gradient algorithm exteuded from the variable struc ture formula and its application to nonlinear systems arc given in this paper. The algorithm can automatically change the model structure.In the practice of the oilfield prediction it has teen proved that the predictor can trace the change of the system structure, thus the predicted precision of variablestructure systems is greatly improved.
