The application discloses a self-adaptive vibration isolation control method for a phase-separated closed bus, and is characterized in that an equivalent fourteen-degree-of-freedom vibration isolation system dynamic model is established in combination with the internal structure of the phase-separated closed bus and the phase interval installation mode of a magneto-rheological elastomer vibration isolator; after input and output variables of the dynamic model are determined, a fuzzy controller is designed, the input variables are fuzzed, fuzzy rules are formulated, and output variables are obtained after defuzzification; and the quantization factor parameters of the fuzzy controller are determined, the calculated control current is output to the magneto-rheological elastomer vibration isolator, and the stiffness and damping of the vibration isolator are changed. The self-adaptive vibration isolation control method can fully exert the mechanical characteristics of variable stiffness and variable damping of the magneto-rheological elastomer vibration isolator, efficiently suppress the vibration generated under normal working and short-circuit current conditions of the phase-separated closed bus, and has important practical significance for ensuring the safety of equipment and the stability of a power system.
