Abstract The improvement of existing electromechanical guidance systems of the armament complex of combat vehicles should be implemented in the direction of increasing the speed and accuracy of positioning. The paper deals with the lifting mechanism of guidance of the package of guides of the multiple rocket launcher BM-21, which is a unit of the armament of the Armed Forces of Ukraine and is typical for many samples of weaponry. Based on the experimentally obtained time dependencies of the coordinates of the existing electromechanical system for providing a vertical motion of a package of guides, the parameters and the transfer functions of its elements have been identified, which have been implemented in the mathematical and computer Simulink-model. The comparison of the processes of changes of coordinates in the guidance process obtained by means of the created computer model and on the operating combat machine has been carried out. The comparisons of the obtained results have shown that the sufficient accuracy of coincidence of the time dependences of the coordinates of the electromechanical guidance systems is attained. Keywords: armament guidance system; positioning accuracy; performance; computer model. 1. Definition of the research problem Modern electromechanical systems of guidance, positioning, and tracking of an armament complex (responsible precise or powerful drives of individual weapons, etc.) are subjected to increased requirements for their performance, static and dynamic positioning accuracy, nature of the transition process, energy characteristics, automation level, etc. [1], [2], [3]. The mentioned indicators can be improved only on the basis of the integrated system approach [4], [5]. One of the expedient ways of obtaining the best solutions based on the specified approach is the use of mathematical and computer simulations [6]. Being performed on computer models, the optimization procedures, taking into account the constraints imposed on the parameters, indicators, and coordinates of the designed electromechanical system, allow us to obtain the structural, system-technical solutions and optimal values of variational parameters for the most complete implementation in the system of guidance of the set requirements to the indicators of its dynamics, statics, reliability, and energy efficiency. 2. Analysis of the recent studies and publications on the problem According to the results of research and the experience of operation of a combat vehicle of multiple rocket launcher, the existing guidance system based on the electric drive according to the "rotary amplifier - direct current (DC) engine" scheme used on this vehicle has exhausted its capacity to increase performance and has the boundary- possible indicators of dynamics and statics of regulation of a package of launch for such systems.
