Abstract: Further solves limits flows the question, is the only way also implements the reaction control to the electric current, how the question is processes between the good speed control and the electric current control relations.After studies and the practice repeatedly, finally discovered, if establishes two regulators in the system, adjusts the rotational speed and the electric current separately, Between both implements the series connection, namely by the rpm control output took current regulator ACR the input, uses the current regulator the output to take the thyristor trigger again the control voltage, then these two kind of control action can coordinate mutually, complemented one another.
Key words: Double closed loop velocity modulation system; Definite integral; Irreversible system
