The operator often need to suit in all respects requisition , such as change from to inertia, fixed position control, fixed velocity control, and operation make for effect of disturbances and measurement noises, upward for factor of uncertainty. The plant is three degree of freedom torsional system ECP205. Design QFT robust controller under parameters uncertainty with unmodeled dynamics, make plant satisfy performances response. The digital controller realize, often discuss difference between the simulations and results of experimental. In addition, the QFT, PD and optimal controllers compare with analysis their robust.
