Solid rocket thrust vector control system and method

The invention relates to the technical field of solid rocket thrust vector control, in particular to a solid rocket thrust vector control system and method. Comprising a plurality of execution mechanisms, a plurality of servo motors, a servo driver, a controller and an upper computer, the servo motors are used for driving the execution mechanisms, and the output end of each servo motor is connected with the input end of the corresponding execution mechanism; the servo drivers are used for driving the servo motors, and the output end of each servo driver is connected with the input end of the corresponding servo motor. The controller is in two-way communication connection with the plurality of servo drivers; and the upper computer is in bidirectional communication connection with the controller. According to the invention, attitude control of the solid rocket engine can be realized. According to the invention, closed-loop control of a current loop and a speed loop and closed-loop control of a position loop can
