Based on the above, we have developed a method of automated pulse control of a multimotor asynchronous electrical drive with the use of bidirectional shift register and resistance boxes in order to provide coordinated rotation of electrical motors [2].
Based on the circuit diagram, we have developed the flow-graph and the graph for the Mealy automaton of the automatic pulse control device for the multimotor asynchronous drive with the use of bidirectional shift registers and resistance boxes (Fig.
Since the number of states in the graph of the synthesized model of the controlling microprogram Mealy automaton is high we have drawn up the structured transition table for the Mealy automaton for automated pulse control of the multimotor asynchronous drive with the use of bidirectional shift registers and resistance boxes (Table I).
