Abstract :
This paper presents a gain adaptation of the current PI controller with consideration of the variable time constant and an EMF compensation for the nonlinear switched reluctance machine. With this it is possible to minimize the disturbances in the control loop, which are related to the saturation or the back EMF. The compensation for each point of operation is done referring to the actual position, current and speed of the machine. Additionally a short comparison of hysteresis and PI controller is presented
