Model Predictive Torque Control of a Switched Reluctance Drive with Heat Dissipation Balancing in a Power Converter

Abstract

The switched reluctance machines are known for their torque pulsations. The precise torque control is usually implemented by varying commutation angles and applying direct torque control. But still the problem of pulsation occurs during phase change. This paper proposes a model predictive direct torque control method, which cost function takes into account both torque and current control including heat dissipation balancing in a power converter. The proposed control strategy was examined using a simulation model and provides precise torque control. Heat dissipation balancing helps to equalize power modules temperature increasing the maximum output power of the power converter.
