| 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. |
