In modern electrical drives, all regulators are implemented in discrete-time domain. The design of the current controller in the continuous time and its following discretization is a common and effective procedure as long as the ratio between the fundamental frequency and the sampling frequency remains sufficiently small. If this condition is violated, the performance of the closed-loop system becomes increasingly poor or even unstable. Literature has proposed some effective strategies to… CONTINUE READING
