Abstract :
A new control concept for dynamic torque control of switched reluctance drives (SRD) is presented. It is based on a novel machine model that can be calculated online without the need of any additional look-up tables. Due to its mathematical structure the proposed model is suitable for accurate simulations and precise online torque control up to maximum speed. All necessary control parameters can be derived by solving equations in a microcontroller, only. Furthermore the torque control using the proposed machine model is very flexible and self adapting to the variation of external parameters (e.g. the DC-link voltage)
