Integration of v-F Facility in Automated Artillery Fire Control System

Automated artillery fire control systems (ACSaf) play an important role in modern combat operations in the border regions of Ukraine. Such systems make it possible to significantly increase the effectiveness of the use of not only individual firearms, but also groups of such systems. Automation of the fire control process ensures prompt transfer (distribution and redistribution) of targets, which leads to an increase in the accuracy and efficiency of the actions of artillery units. In practice, existing ACSaf have a number of disadvantages, such as complexity, cost, and long development times. The presence and use on the front of artillery systems developed in the last century and by different manufacturers makes it much more difficult (and sometimes impossible) to implement the ACSaf, due to the lack of unification and standardization of components. One of the ways of development and improvement of ACSaf is the introduction of a unified system of automated control (SAC) of an object of the vehicle-firearm type (V-F). Such an automatic control system can be used as a basis for the development of new ACSaf, as well as for the modernization of existing ones. The article examines the principles and tasks of ACS artillery fire, and also suggests the direction of their improvement with the help of V-F SAC. In classic problems of the theory of automatic control, it is often necessary to take into account restrictions on state variables. The presence of such limitations is considered in the framework of two approaches. Restrictions can be considered as certain conditions, the fulfillment of which is not guaranteed by the physical properties of the object and must be ensured by a proper choice of management. In the second approach, constraints on the state variables are taken into account by introducing nonlinear static characteristics with saturation. At the same time, in the object model, restrictions are imposed not on the vector of state variables, but on the vector of their derivatives - input signals of individual links of the system. It is, in general, possible for the state variables to go beyond the limits defined by static nonlinearities.
