| Abstract: | For accelerating estimation speed of the load torque for AC servo system, a new model of the reduce-order observer is brought up. Based on the reduced-order observer, a new model of the reduce-order observer is brought up and estimate the load torque, its validity is analyzed by the simulation. The simulation result shows that the model is valid and can obviously improve the convergent speed of estimation algorithm. |
