Abstract :
Many electrical machines are nowadays controlled using digital controllers resulting in variable-speed drives. To enhance control engineers want to deal with the switching behaviour of the power converters or pulse-width modulation in more detail. To help them, in this paper, a previously proposed enhanced discrete-time model in the z-domain is applied to machine drives. Additionally, the application of a discrete-time anti-windup method for three-phase machines is presented.
