Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Actuating mechanism control – modern lines Pak V.S., Sorokin V.V., Ulitenko K.J., Fedin G.V. The basic requirements demanded from the control facilities of actuating reversive electric mechanisms, equipped by primary sensors of actuating mechanisms position are formulated. Structures of control blocks for single-phase and three-phase reversive electric motors are resulted. Blocks are functionally finished products for the realization both in local, and in the distributed automated control systems (ACS) and include modern options, such as the communication with top level of ACS of technological process on the digital channel and the maintenance of the drive control through the radio channel.
