The methodological approaches to the improvement of the control system of the vertical guidance mechanism of FM-21 multiple launch missile system to increasing its speed and positioning accuracy are confirmed. The use of the three-circuit positional structure of the control system of the guidance mechanism with a position control loop and a fuzzy corrector is justified. A mathematical model of the guiding package motion has been obtained and its reaction has been calculated. The parameters of the electrical and mechanical elements of a guidance system and their transient characteristics are experimentally obtained. With the use of the approximation procedure, the analytical dependencies of these transient characteristics and corresponding transient functions of various orders of the elements of an electric drive power circuit are obtained.
