On the basis of theoretical and practical studies of the multivariate electromechanical system, the scientific and technical problem of improving the control system of the electromechanical system during the influence of multi-vector perturbations on it is solved. The result of the research is the combination of equations in the system of differential equations with coefficients dependent on the fluctuations of the control object. In the theoretical part the mathematical model of the electromechanical system was synthesized, which made it possible to investigate ways of minimizing the angles of deviation and time intervals necessary to stabilize the movement of the electromechanical system, which made it possible indirectly to implement the signal associated with the stochastic nature of the moment of the control object fluctuation on coordinate plane. The method of parametric optimization of the mathematical model of the electromechanical system in the deviation angle function was also improved and investigated. Based on the determination of the structure and algorithms of work, the efficiency of the control system of the electromechanical system is increased in terms of reducing the time of stabilization of the control object.
