The invention belongs to the technical field of control technology and metal forming, and particularly relates to a limited control set-based sensorless press machine full-closed-loop control system and method. According to the system and method, the difference between a forming process curve and the actual position of a sliding block is used as a whole machine control system control instruction position input, a kinetic model is established, torque calculation is carried out, and the calculated result is taken as an input of a torque prediction control algorithm. The system and method have the advantages that a non-sensing control algorithm module and a torque prediction algorithm module of a limited control set are arranged in a servo motor driver, the rotating speed and the electromagnetic torque prediction value are calculated, the value function is finally obtained, the position information of the sliding block can be added into the value function to control the position of the sliding block to not be overly controlled, the dynamic performance is obviously improved, the anti-interference performance of the motor servo driver can be improved, the reliability is remarkably improved, and the cost of a servo motor is greatly reduced.
