Kostik B. Increasing the accuracy and speed of the automatic phase control systems with differential communication

The given papers considers the problems of increasing the accuracy and speed of the automatic phase control systems with differential com-munication. It presents some new structures of automatic phase control systems with differential communication which allow to synthesize the automatic phase control systems of high accuracy by comparatively simple technical methods. There has been done a comparative analysis of the combined automatic phase control systems with differential commu-nication with differential communication, their equivalent conditions being obtained. It has been demonstrated that the differential communica-tion operator of the automatic phase control system with differential communication in case of equivalent conditions does not influence the invariant conditions and the closed circuit stability of the automatic phase control system. On the basis of K(D) representations there have been developed some methods of synthesizing parameters of the automatic phase control system in case of increasing the accuracy within set modes, the conditions of the physical realization of the differential communica-tion operator being considered.
