| Popis: | 81 A multi-input/multi-output single-axis slewing control simulation and experiment is presented in this paper. The system includes a flexible beamclammped to a stepping motor, which prov- ides hub anglar position control andmeasurement. A strain gauge and a piezoelectric material is attached to either side of the beam for measuring the structural deflections and controlling beam vibration,respectively. Nonlinear control effects in the stepping motor and the piezoelectric material due to dead zone and satuations were considered. A natural control method was pro- posed using both actuators for simultaneous position and vibr- ation controll. Test examples with comparision to other control methods indicate that efficient and improved control performance can be achieved with the proposed control method. |
