The invention discloses an electro-hydraulic actuator control system. The electro-hydraulic actuator control system comprises a power module, a signal collecting module, a signal processing module anda driving module. According to the power module provided by the invention, the alternate current side is subjected to overcurrent protection through a fuse, a surge suppressor achieves lightning protection and surge protection, an alternating current filter achieves the alternate current side filtering function, then, AC-DC switching is achieved through a linear power circuit, a direct current power source is input into a direct current filter to achieve the filtering and signal stabilizing functions and is converted into a plurality of direct current power sources through a DC-DC and voltageadjusting device, a power source system applied to complex working conditions is formed, and a stable work power source is provided for the electro-hydraulic actuator control system.
