摘要
A multi-phase induction motor torque control method comprising the steps of establishing an adaptive speed observer and an adaptive flux observer using a speed sensorless control scheme. Rotor speed is estimated based on filtered current and voltage command signals as inputs. A flux observer based on the estimated rotor speed and rotor flux angle is calculated using the estimated rotor flux. Torque is determined following estimation of speed and flux.
