摘要

The feedback control is obtained using detectors (6), an observer (5) and a computer (4) to determine inverter switching. The control aims to align torque and stator flux with set values. Measurements are taken over a half-period in the inverter switching cycle. The control signals are determined by solution of a set of differential equations using time derivatives of torque.
