Abstract
Interior permanent magnet synchronous motors can be applied to applications requiring wide-speed operation. The current control scheme of an interior permanent magnet synchronous (IPM) motor via feedback linearizing technique is proposed. As the available voltage controlling the armature current is small in transient operations and/or flux-weakening region, the current control performance can be deteriorated. The high performance overmodulation strategy is also proposed to improve the current responses. The control performances are confirmed by simulations.
