A rudder control system of an underwater high-speed vehicle is composed of a main control panel and a linear servo motor; specifically, the invention provides the rudder control system of the underwater high-speed vehicle, which is composed of the main control panel based on a DSP (Digital Signal Processor) processing chip and the linear servo motor using an H-bridge circuit as a drive circuit. The control system is designed to be a single closed-loop link; a feedback signal is position information of the servo motor; and the position information of the servo motor is also used as rudder angle change information. A feedback branch adopts information of the servo motor acquired by a photoelectric encoder; the position information of the motor is transmitted to an upper computer by a DSPF2812 and is processed by the upper computer and then converted into a depth signal of an actual navigation vehicle. After the difference between a given depth and an actual depth is calculated, the upper computer transmits the difference value to the DSPF2812, treats the difference value in the DSP by means of a PID (Positional Integral Differential) algorithm, finally, generates impulse waveforms with certain duty ratio as well as directional control signals of the servo motor according to the output of the PID and controls the rotation of the servo motor by means of the drive circuit of the motor.
