DEVICE FOR SIMULATION OF NONLINEAR MODELS OF PHYSICAL OBJECTS

摘要

The invention relates to simulation in control of objects having physical nature. A device for simulation of nonlinear models of physical objects comprises an interpolator and a corrector. There is an additional data input unit, a unit for indicating direction of components of a linear response function gradient, a unit of combinatorial searching of candidate models, the second interpolator and a model quality sensor. The output of the first interpolator is connected to the first input of the unit for indicating direction of components of a linear response function gradient which second input is connected to the output of data input unit, which output is connected also with the first interpolator input. The output of the unit for indicating direction of components of a linear response function gradient is connected to the first input of the unit of combinatorial searching of candidate models, which output is connected to the input of the second interpolator. The output of the second interpolator is connected to the first input of the corrector, which second input is connected to the model quality sensor, and the corrector output is connected to the second input of the unit of combinatorial searching of candidate models. The device provides increase of accuracy and improvement of extrapolation properties of nonlinear model.
