The study objective is to find out the regularity of attractive force change of the friction surfaces of the adaptive friction clutch in order to ensure a particularly high tear-and-wear accuracy. The task to which the paper is devoted is presentation of various analysis and synthesis stages of the control device of the adaptive friction clutch with positive feedback. Research methods: developed and previously applied elements of the theory of adaptive safety friction clutch with positive feedback and full stabilization of limiting torque allow to make a knowledge base of particular mathematical models that locally describe the process of automatic regulation of the control device. Based on the analysis of the applied method of mathematical modeling, it is found out that it is possible to use synthesized structural and functional diagrams of the control device of positive feedback in clutches in order to ensure high accuracy of their operation. The novelty of the work is that ensuring high stabilization of the limiting torque of the adaptive friction clutch with positive feedback is possible because of the control device structure with a variable ratio value of feedback gain. Study results: the use of the control device with a variable ratio value of feedback gain gives the opportunity to provide particularly high stability of the limiting torque of the adaptive friction clutch. Conclusions: in order to ensure a high stability of the limiting torque of the adaptive friction clutch s with a positive feedback, a special construction of the control device has to be installed in accordance with the dependencies found in its parameters.
