Multi-mass system with elastic coupling is one of the most complex dynamical systems. Complexity in such systems is the elastic mechanical coupling and the effect of the backslash as well as the external disturbances (wind), because of which there is a continuous self-oscillation in the transient response. This article suggests a solution for such systems, the controller algorithm combines the modal control and adaptive control with reference model. The three-mass radio telescope RT70 model is used as an object of study. The results obtained in the environment of MATLAB-SIMULINK, show that the modal-adaptive control of the drive successfully achieved great performance, excluding the effect of the backslash and the effective suppression of the wind loads on the telescope. The description of the radio telescope used in this article, excluding the fourth weight –the counterweight.
