Simulation of a torque based hysteresis control in static and low dynamic conditions

The simulation of a direct torque hysteresis controller (DTHC) driving an interior permanent magnet synchronous machine (IPMSM) is presented in this paper. The underlying switching concept as well as a proposed experimental setup is discussed. Various simulations, varying the torque and current tolerances, are carried out in the low torque and high torque range. Simulation results show a direct influence on the switching frequency and load of the utilized voltage source inverter which can be minimized and balanced, respectively, by the application of a DTHC.
