The invention belongs to the technical field of flight control, and relates to an aircraft pitching control surface clamping stagnation influence suppression method and device based on thrust control. The method comprises the following steps: acquiring a longitudinal trajectory angle, a vertical speed and a pitch angle rate of an aircraft; when the longitudinal track angle is larger than the track angle threshold value and the vertical speed is larger than the speed threshold value, longitudinal transition state control is carried out, the instruction that the longitudinal track angle is equal to 0 serves as the track angle, the difference between the current longitudinal track angle of the aircraft and the track angle instruction is obtained, and proportional-integral control is used for obtaining a first throttle lever position instruction; after proportional gain is conducted on the vertical speed, the vertical speed is superposed on the first throttle lever position instruction in a negative feedback mode, and a second throttle lever position instruction is formed; after proportional gain is conducted on the pitch angle rate, the pitch angle rate is superposed on the second throttle lever position instruction in a negative feedback mode, and a third throttle lever position instruction is formed; and controlling an aircraft engine to provide thrust according to the third throttle lever position instruction. According to the invention, the safety of flight control is improved.
