The invention discloses a position feedback control servo motor driving system, comprising a control stick grip, a transmission mechanism, an angular displacement sensor, a control platform, and a motor. The motor is connected with the transmission mechanism and the control platform. The angular displacement sensor is arranged on the transmission mechanism, and is connected with the control platform. A control cabinet and a driving cabinet are connected with the transmission mechanism. A ground-based simulation platform is connected with the control cabinet through an intelligent transceiver. The control cabinet, the driving cabinet, and the ground-based simulation platform are connected with a power cabinet. Using the system, a driver just needs a handle to input instructions to operate a control stick, the instructions are transmitted to the control platform through a position sensor, a position closed-loop compares the values measured by the position sensor with a target position instruction given by an upper host, and then calculates errors, a PID control module of a controller CPU calculates variation amount of SPWM duty ratio, so as to control rotating speed of the motor, so that the control stick grip gradually approaches a target position.
