The invention discloses a parafoil servo control method without a current sensor, which solves the problem that three-loop control cannot be closed under the working conditions of large tension load and high-speed servo of a parafoil, establishes a current estimator as the feedback of a current loop, and completes the closed loop of the current loop. The conditions of tension moment compensation of parachute cords at different positions are obtained through dynamic simulation calculation of the parafoil and are introduced into three-ring control, so that high-precision servo control of the high-speed and large-load parafoil without a current sensor is achieved, and the method is suitable for the field of intelligent recovery of aviation and spaceflight.
