The parametric identification of the mechanism of vertical guidance of the support-rotary device of the measuring antenna complex is carried out. The transfer function is defined, which is presented as a model of the control object. The results of experimental studies allow to determine the average speed of movement of the pivoting device on the corner of the place with the required supply voltage. An integrator and a transfer function of the controller are introduced into the algorithm of the control scheme of the object position. The developed scheme of the control system allows to provide the dynamics corresponding to this speed. The block diagram of the control system implementing the necessary dynamics of the object is given. The control algorithm with the controller is studied using the Matlab 7.9.0 software package. The article presents the logarithmic frequency characteristics of open and closed systems. According to the results of the proposed method of synthesis of the controller for the device, the time of the transient process of the installation is determined; a smooth stop of the device is provided, oscillations are eliminated.
