Abstract :
This paper investigates the on-line reconstruction of magnetisation curves, flux linkage/current (psi/i) loops and loop torque estimation for switched reluctance machines, including the effects of mutual coupling. The techniques are based on phase current sensing and the reconstruction of phase voltage using the DC Link voltage, the PWM duty cycle and inverter device loss compensation. Tests are included for a 4 phase 8:6 1 HP switched reluctance machine, the results showing good correlation with existing direct measurement techniques. It is proposed that the presented estimation techniques can be used in machine parameter identification, optimised control, and fault detection/management.
