Through MATLAB simulation and follow-up experiments at set speed of 500 r/min and 1 000 r/min, the effect of simulation system working with a driving control system was studied. Results show that the proposed system can simulate internal structure of AC permanent magnet servo motor and the load to collect three phase currents, can calculate the rotation speed and rotation angle of the servo system with the relative error of calculation speed less than 10%. The proposed system can recreate working condition of the AC permanent magnet servo motor and the load, simulate the accurate speed and position feedback signal, and quickly realize the inspection of the servo system.
