ABSTRAKT

The problem of the effect of different types of consensus on digital redundant asynchronous control systems dynamics is considered. Typical cases of data equalization are analyzed, including inputs to the system and outputs of its integrators and filters. Frequency response methods of analysis are used. Additional lag due to equalization of input data, as well as the effect of equalization of output data on the integrator gain and the filter time constant, is estimated. Stability margins are calculated with data equalization for continuous control, digital, and digital redundant systems.
