✦ Synopsis
The paper considers the problem of regulation of velocity and rotor #ux norm of an induction motor. The rotor #ux is assumed unmeasurable, load torque and rotor resistance may be unknown and time varying, with small non-di!erentiable disturbances present. A simple and robust discrete-time control technique is justi"ed theoretically and tested experimentally. It can be considered as a generalization and modi"cation of "eld oriented control. In its &non-adaptive' modi"cation, it ensures global exponential stability of a closedloop system, if at least local stabilization of the system by static control is possible, for given parameter estimates. In adaptive version it provides identi"cation and global exponential stabilization of the system.
