Abstract:
The mathematical modeling on the computer allows to receive an estimation of properties of system with use of means of graphic visualization. As object of modeling the system of prompting of a rocket of a class «air - air» aboard the plane - purpose is considered which as protection applies a towed or shot trap with transmitter. For construction of model of system of prompting the models of components of system are constructed which as subsystems were united together according to structure of initial object. The movement of the plane - target was set on the basis of the known equations, and rocket by system of the equations for symmetric of object. The parameters of relative movement of objects pay off in subsystem kinematical of a link, which part is realized by means of a package of visualization, and part as the program. The author offers a method of modeling of processing of signals in systems with nonlinear by the characteristic on an input. Up to the discriminator the size of signals meets only to sizes of parameters and does not carry the information on amplitude of a real signal. Only on an output in size of a signal the amplitude of an entrance signal was taken into account. As the size of entrance signals for the purpose and trap corresponds to size of parameters, the simultaneous processing in the discriminator is not possible. She is made separately in completely identical pairs channels. Thus, the model is realized as the enclosed each other subsystems, that has allowed to receive rather simple in use and at the same time rather complex, reflecting many detail of a reality model. In clause nothing is told about preference in a choice of that or other way of realization of model. It - question of separate discussion, and frequently decision is - accepted proceeding from practical reasons. The offered model is simple in application and is evident. Besides it has some latent reserves connected to opportunities on change and complication of structure of model and its internal connections. Use of means of visualization allows even the beginning researcher to avoid some mistakes connected to modeling at application of standard means and methods.
