CONVERSION SIGNIFICANTLY NONLINEAR OBJECTS’ EQUATION TO QUASILINEAR MODELS
The design problem of the quasilinear models of significantly nonlinear objects with differentiable nonlinearities is considered. These models are traditionally created with use of partial derivatives and the subsequent integration of these derivatives on the auxiliary variable. However often the nonlinearities of the objects have so difficult character that the operations of differentiation and, in particular, integration it is quite difficult to execute. The numerical design method of quasilinear models which excludes need of application of the known differentiation and integration formulas is developed for overcoming this complexity. This method can be applied to the nonlinear control systems design for the significantly nonlinear objects of ship, aviation, chemical, agricultural and other industries.
