Abstract:Indirect field oriented control of induction machine is widely used in a lot of industrial applications. The performance of the control scheme, however, strongly relies on the parameters of the motor, e.g. the rotor resistance and mutual inductance between rotor and stator of the motor. The variance of the parameters in operation results in decline of the control, that is vital especially for the torque control in electric vehicles. In this paper, the effects of parameter errors including rotor resistance and mutual inductance, on the rotor flux and the electromagnetic torque are discussed in details. A new scheme of tuning parameters on-line via the steady state voltage model based rotor flux estimation is proposed, in which the inverses of rotor time constant and mutual inductance are corrected by the error of phase angle and magnitude of the rotor flux. The simulation and experiment results validate the effectiveness in improving torque control of the new method.
