Abstract :
This paper combines active disturbances rejection control technology with fuzzy control technology, puts forward a novel servo system position control method based on active disturbances rejection fuzzy (ADR-FUZZY) theory. The experimental results show that active disturbances rejection fuzzy position controller has high tracking precision, quick response time and favorable control effect as well as preferable robustness to model´s uncertainty and noise measurement. The proposed method solves several difficult problems of servo system position control, such as input signal smoothing, motional disturbance, and hard matching among parameters due to strict requirements on system precision, stability and quick response in position control
