Zhu, Z.Q., Chen, Y.S. and Howe, D. (2000) Online optimal flux-weakening control of permanent-magnet brushless AC drives. IEEE Transactions on Industry Applications, 36 (5). pp. 1661-1668. ISSN 0093-9994
Abstract
An enhanced online optimal control strategy, which maximizes the flux-weakening performance of a brushless AC motor, is described, and applied to motors having different rotor topologies: interior (radial or circumferential), inset, and surface-mounted magnet. It enables the maximum inherent power capability of a brushless AC motor to be achieved independent of any variation in its parameters, and facilitates maximum efficiency over the entire speed range. It also results in good transient dynamic performance, since it is coupled with feedforward vector control based on optimal current profiles.
