The invention discloses a rudder angle control device for an embedded water tunnel test. The device comprises a servo driving device, a hydraulic follow-up device and a steering device which are connected in sequence, the steering device is connected with one end of a rudder shaft, the other end of the rudder shaft is fixedly connected with a rudder, and the middle of the rudder shaft is movably connected with an aircraft model shell; an upper computer sends a rudder angle instruction to a motor driver and a servo motor, rotation of the servo motor is converted into translation of a piston ofthe driving hydraulic cylinder through a ball screw composed of a lead screw and a lead screw nut, a position sensor feeds back the position of the piston of the driving hydraulic cylinder in real time to form proportional differential closed-loop control, and then accurate control over the position is achieved. A follow-up hydraulic cylinder piston in the hydraulic follow-up system accurately follows the movement of a driving hydraulic cylinder piston, and then the translational motion of the follow-up hydraulic cylinder piston is converted into the rotation of a rudder shaft through a connecting rod and a swing rod of the steering device, so that the accurate transmission of the position is realized. According to the principle, the rudder angle control device is designed, and the rudderangle can be accurately controlled under the cooperation of all parts.
