Abstract :
The authors introduce a load speed feedback control to prevent the mechanically-resonant vibration in AC servo motor drive motion system with two-mass mechanical motion load. In order to compensate three characteristic system gain parameters, the /spl alpha/-parameter ultimate sensitivity method based on partial model matching method is proposed. Moreover, a fuzzy reasoning algorithm is applied to compensate this parameter /spl alpha/. The effectiveness of this advanced auto-tuning control scheme in the AC speed servo system is verified by computer simulation.
