The application of a direct torque hysteresis controller (DTHC) driving an interior permanent magnet synchronous machine (IPMSM) in the dynamic state is presented in this paper. The underlying switching concept as well as a proposed experimental setup is discussed. Positive and negative torque setpoint steps are simulated in the low torque and high torque range. Simulation results show that the number...
In this paper, a direct torque hysteresis controller (DTHC) driving a permanent magnet synchronous machine is discussed. A two-level, three-phase conventional inverter is used as means of power conversion. Advantages such as a low switching frequency as well as further opportunities of the DTHC are specified. The simulation results show a high degree of potential for the DTHC in future applications.
