For the decline of the control accuracy of servo system due to the disturbances of load, to design the dimensionality reduction load torque observer, the observed value of load torque after conversion for compensation control. Established the three- loop mathematical model of servo control system, to elicit three- loop control parameter setting formula by the application of optimal second order and third order model theory. Established the simulation model of space vector control AC servo system, by simulation experiment it is verified that three-ring parameters can provide good dynamic performance for system after setting. After the establishment of experimental platform, through the motor load sudden change experiment, it proved the feasibility of the torque compensation control for improving the servo system control precision under load disturbances.
