The invention relates to an intelligent electro-hydraulic actuator self-healing regulation and control system control method, which comprises the steps of collecting on-site incoming signals when the intelligent electro-hydraulic actuator is in work state, wherein the on-site incoming signals comprise a sensor signal, a hydraulic control valve signal, a controller signal, an oil pump signal and/or a power supply system signal. The beneficial effects of the present invention are that thanks to the comprehensive realization of the EHS intelligent electro-hydraulic actuator control system self-healing function, the apparatus reliability is greatly lifted; advantages like strong maintainability and high intelligent degree are provided; few technology personnel are required to diagnose and maintain the fault; the fault processing time is close to 0; maintenance can be done without shutdown the apparatus and temporary shutdown is avoided; influence to control and production prevented in the maintenance process; harm to the apparatus and the controlled object is prevented; and accident to safety and production is prevented; the system is in good state again after the maintenance; and a catalytic cracking apparatus can be ensured for stationary operation.
