Nonlinear Adaptive Control Of A Synchronous Machine
Betz RE., Evans RJ.
A nonlinear adaptive controller for a load-commutated brushless dc machine that allows the machine to develop high torque over a wide range of operating conditions, while satisfying voltage and current constraints on both stator and field circuits, is presented. The approach taken is fundamentally different from past work in that a nonlinear control is formulated from the steady-state model of the synchronous machine. Adaptive algorithms are presented for both the unknown load and motor cases. Copyright © 1985 by The Institute of Electncal and Electronics Engineers, Inc.
