Modelling and identification of synchronous machines has attracted much attention during the past decades. Although the standstill frequency response (SSFR) method has become standardized (IEEE Std. 115) it has some disadvantages (e.g. it is a time consuming method). To overcome these, the use of broadband excitation has been proposed in the literature. In(More)
This paper discusses fundamental equations which can be used in high-frequency signal based position estimators for synchronous machines. For this purpose, a small signal dynamic flux model is presented that takes into account the nonlinear magnetic condition and the magnetic interaction between the two orthogonal magnetic axes. The derivation of this model(More)
Nowadays numerous techniques to model the behaviour of electrical drives are discussed in the literature. In many cases a linear magnetic network is proposed. This paper proposes a large-signal simulation model of an induction machine that takes into account the magnetizing-flux saturation. The model is given as a state-space model with nonlinear feedback(More)
A new space vector torque control strategy is developed for switched reluctance machines. The method is based on an existing space vector control strategy, which yields an explicit expression for the phase currents realizing a desired torque at a given rotor position. With the improved strategy, a higher torque-current ratio is achieved. A new approach(More)
In this paper a nonlinear model for AC machines is proposed that takes into account the magnetic saturation and magnetic interaction between both orthogonal magnetic axes. Furthermore, the model includes the presence of air-gap flux harmonic components caused by magnetic saturation and multiple-pole spatial saliencies. Such a model is used to describe in a(More)
