Abstract :
In this paper an approach to estimate the speed and the stator flux linkage of a three Phase induction motor by means of an algorithm using dSPACE is proposed. Emphasis is given on reduction of the problem of saturation associated with the pure integrator, while flux estimation. Speed is estimated using a sensor (MOC7811) mounted at the motor shaft. Experimental investigation is carried out on a 1 H.P. motor, a digital inverter controller, an IGBT power module for inverter/chopper and dSPACE Controller Board (CP1104). Real time signals like three phase currents, PWM Pulses, fixed DC link voltage and response of sensor MOC7811 are the input parameters to the Dspace controller board, and using these parameters stator flux and speed is estimated.
