摘要
This paper presents a new simplified speed-sensorless vector control method for induction motors. The output voltage of the d-axis PI current controller with a decoupling control is used to compute the flux angle and to control the speed in correspondence with its reference. System stability is discussed by the root loci computed from a linear model. The effectiveness of the proposed method is demonstrated by nonlinear simulations and experiments.
