Abstract :
The problem of induction motor state estimation and control without AC current measurements is considered. A state observer is designed by using a suitably reformulated output equation of the motor dynamic model. A field oriented control scheme and a decoupling controller with two independent current control loops is also presented. The proposed scheme is suitable for series hybrid electric vehicles, so as confirmed by-simulations carried out with Matlab/Simulink
