The invention discloses a control system and method for a rectifier of a charging pile of an electric vehicle. The control system comprises a direct-current-side voltage sensor, an alternating-current-side voltage sensor, a current sensor, an active disturbance rejection control module with a reduced-order expansion state observer, a PI controller, a coordinate transformation module, a nonlinear decoupling module and an SVPWM module, wherein the alternating-current-side voltage sensor and the current sensor are connected with the input end of the coordinate conversion module, and the coordinate conversion module and the direct-current-side voltage sensor are jointly connected with the active disturbance rejection control module; the active disturbance rejection control module is connected with the PI controller; the PI controller is connected with the nonlinear decoupling module; the nonlinear decoupling module is connected with the SVPWM module; and the SVPWM module is connected with a rectifier bridge circuit in the rectifier. According to the invention, by using the active disturbance rejection control module with the reduced-order expansion state observer, the order of the observer is effectively reduced.
