The paper describes implementation and operational features of the object transfer systems in the working space of simulators for training cosmonauts to fulfill extravehicular activity in non-gravity and reduced gravity environment. The control system design concepts of cosmonauts' horizontal movements under non-gravity and reduced gravity environment simulation were studied. It was proved necessary to apply electromechanical systems for friction and inertial force compensation by additionally joined masses to the non-gravity object while implementing advanced simulators. The control system structure was developed; it contains feedbacks on current, speed and electric drive shaft accelerations, as well as on belt transmission force and power drive cable deflection angle from the perpendicular position. The paper presents the results of synthesizing the cosmonauts' movement control system structure in the working space of simulators, as well as of correcting device parameters to provide damping of springy oscillations in machinery.
