The first implementations of electrical machine control algorithms were based on analog solutions. Although these analog solutions are criticized for a number of shortcomings, they nevertheless retain certain fundamental advantages, where the transition to digital is problematic (see [D 3 640] Digital machine control. Control evolution ). These fundamental advantages are essentially speed (analog control responses are almost instantaneous) and continuous action. As a result, analog controls can be used to achieve high bandwidth control. Digital solutions, on the other hand, appear slower and handle...
