The invention discloses a fractional order PID control method for an automobile steer-by-wire system. The automobile steer-by-wire system mainly comprises an electronic control unit module, a steering wheel module, a steering motor module, a front-wheel steering module and the like, and the transfer function of each simultaneous module can obtain the transfer function of the dynamics of the automobile steer-by-wire system. In combination with the transfer function and fractional order PID of the system, control the transfer function to obtain the phase angle and gain of an open-loop system, and according to the stability margin index of the open-loop system, use the Particle Swarm Optimization to calculate and obtain the control parameters Kp, KI, KD, Lambada and nu of the fractional order PID controller. The controlled quantity obtained through the calculation of the fractional order PID controller drives the steering motor to make the steering motor output an ideal steering torque. The control strategy described by the fractional order PID control method can realize the ideal control of the automobile steer-by-wire system and improve the robustness and steady-state performance of the system; the fractional order PID control method adopts floating-point type TIDSP28355 as the core processor so as to carry out the high-efficiency treatment operation on fractional calculus.
