Abstract :
In this paper, in order to suppress the mechanical resonance and anti-resonance in a DC brushless motor-based AC speed servo system with two-mass mechanical motion load, a load speed observer with a load disturbance estimating function which is suitable for the load speed feedback compensation is proposed. Then, the gain parameters auto-tuning control implementation which is based on fuzzy reasoning with the observer-based load speed feedback compensation in addition to the conventional PI compensation is proposed and discussed from experimental point of view
