... of a spinning shaft, which is driven by a nonideal dc motor. A drive whose dynamics is influenced by the dynamics of the driven system is called a nonideal source and the whole system is referred to as a nonideal system. In particular, we show the advantages of representing such nonideal drive-system...

...Rainer Leuschke; Brian C. Fabien This paper presents a technique for attenuating the external disturbances acting on the rotor of a prototype flywheel energy storage device. The approach uses a three-phase axial flux brushless dc motor to simultaneously produce a torque and a radial force...

...-integral-derivative (PID) and more general types of fractional-order QFT controllers for a fractional-order plant, a DC motor, and a multistage flash desalination process. In the proposed approach to the synthesis of fractional-order QFT controllers, the synthesis problem is first posed as a constrained...

...Karim A. Tahboub; Harry H. Asada This paper presents kinematic and dynamic analysis of a holonomic vehicle with continuously-variable transmission. Four ball wheels, independently actuated by DC motors, enable for moving the vehicle in any direction within the plane and rotating it around its...
