This paper introduces designing of a Takagi-Sugeno (T-S) fuzzy, state feedback controller so as to have optimal and robust full-range speed control over the wounded rotor induction motor. A slip energy recovery drive system, using 12-pulse converter and a shunt chopper is used as a modified system to drive a slip ring induction motor, which is coupled with a class of nonlinear uncertain load. Using...
A dynamic decoupling control approach based on inverse system theory is developed for the electric spindle system supported by 5 degree-of-freedom (DOF) AC active magnetic bearings(AMB), which is multi-variable, nonlinear and strong coupling system. The state equations of the 5-DOF AC AMB are set up based on the configuration of 5-DOF AC AMB being introduced and mathematical models of axial and radial...
In industrial world, direct drives are more and more used and rise up new control issues when parameter variations occur. New methods have been created, however, high cost computer and expert is often needed to implement them. In this paper, state feedback controller optimized by linear quadratic principle are shown up. These methods achieve cost requirement cause they provide lighter regulators with...
