Abstract :
This paper presents a neural estimator of torque and stator flux, based on knowledge of stator current and speed. The suggested estimator is constructed from a multilayer feedforward neural network. Training sets are based on calculations using an FEM model of an induction machine. The steady-state performance of an AC motor has been assumed and the nonlinearity of the laminated core has been taken into consideration while modelling the problem. The end-region´s impedance has been considered by means of modification of the rotor cage conductivity
