Control method and control system of servo electric screwdriver

The invention discloses a control method and a control system of a servo electric screwdriver. The control method comprises the steps that preset servo parameters of the servo electric screwdriver are configured, and the preset servo parameters are obtained from a database; a controller is started to input preset servo parameters so as to enable the servo electric screwdriver to operate, and a torque value is detected through real-time torque so as to construct a torque curve model; whether the torque value of the torque curve model exceeds a preset range within a preset time or not is judged to obtain a judgment result; a preset servo parameter is adjusted according to the judgment result; and the controller is started to input the adjusted servo parameters so as to enable the servo electric screwdriver to operate, and a torque value is detected through real-time torque so as to construct a new torque curve model. According to the method, the torque curve is constructed according to real-time data of the ser
