The invention relates to the technical field of emergency equipment, and discloses a pontoon bridge power unit accelerator control system and method.The target position of a power unit is determined through a differential positioning module, and the current position is measured; receiving the target position and the current position through a comparison and judgment module, obtaining a deviation value between the target position and the current position, comparing the deviation value with a set steady-state error, and outputting a comparison result to a position controller; the current position is output to the conversion module through the position controller according to the received comparison result when the requirement is not met; converting the current position into a target rotating speed through a conversion module; detecting the current rotating speed of the servo motor through a rotating speed feedback module; and receiving the target rotating speed and the current rotating speed through a PID control module, obtaining a speed difference value, carrying out PID operation, continuously adjusting to enable the speed difference value to be zero, outputting a speed adjusting signal, controlling a servo motor to run to reach the target speed, and driving an accelerator executing mechanism to act. The response speed and the positioning precision can be improved.
