Abstract
Aiming at characteristics of unpredictability the load torque used in AC motor servo system, a method of load torque adaptive identification based on state observer is presented. First, design the state observer and confirm its stability by Lyapunov function. Second, introduce the load torque identification rate by using torque equation. Finally, prove its effects by experiment under MATLAB/SIMULINK simulation platform. Result shows the load torque identification method has high identification precision and the system exhibits a good dynamic and steady-state performance.关键词
