Discrete-time Method for Robust Global Stabilization of Induction Motors
The paper considers the problem of regulation of velocity and rotor flux norm of an induction motor. The rotor flux is assumed unmeasurable, load torque and rotor resistance may be unknown and time varying, with small non-differentiable disturbances present. A simple and robust discrete-time control technique is justified theoretically and tested experimentally. It can be considered as a generalization and modification of field oriented control. In its non-adaptive modification, it ensures global exponential stability of a closed-loop system, if at least local stabilization of the system by static control is possible, for given parameter estimates. In adaptive version it provides identification and global exponential stabilization of the system. Copyright © 2000 John Wiley & Sons, Ltd.
