摘要：
Proportional Integral (PI) controller based current control is widely employed in different motor drives. However, in case of switched reluctance motor (SRM), the non-linearity and double saliency of the motor make the modelling and controller design challenging. This paper attempts linearisation of the flux linkage characteristic of the SRM at different operating points. The models include saturation and back-emf in an effective manner, as compared to existing methods. The different linearised models are evaluated for the purpose of current controller design. An effective method of controller design is found which directly relates the machine parameters to the controller gains.
