Abstract :
The authors describe the design method for a robust adaptive sliding observer which realizes speed-sensorless field-oriented vector control of AC motor drives. The speed-sensorless field oriented vector control system using the adaptive sliding observer was implemented. The basic characteristics of the proposed system and the design method against parameter deviation were studied experimentally. In the present system, the steady state error of the speed control was about 0.3% and the settling time was about 100 ms. The proposed system had good characteristics of speed control even in a low-speed region. The pole assignment, considering H∞ norm of the transfer function from disturbances, realized good characteristics of the speed-sensorless field-oriented vector control even with parameter deviations
