Dealing with cascade control of electrical feed drives involves optimizing the current loop regarding precision, dynamics, robustness and energy efficiency. This is challenging using switching inverters with pulse width modulation. A direct method based on a switching controller is presented, which needs no downstream modulator. Control takes place in field-oriented as well as in phase-oriented coordinates of the machine, providing benefits compared to other direct methods. Control rules and structures are derived and a comparison between conventional and novel approach is shown. Implementation and measurement were performed in a practical setup, proving higher dynamics and less energy consumption.
