This paper proposes a direct flux vector control strategy with no need for regulators tuning, suitable for permanent-magnet (PM) synchronous machine drives. The controller operates in stator flux coordinates and calculates the inverter reference voltages in a model-based fashion, taking advantage of a novel equation for the explicit evaluation of the torque angle error. The inverter current and voltage limits are exploited in a parameter-independent way. The method segregates the machine parameters into a single block, to make it very easy to switch from one machine to another. Experimental results are reported for a PM-assisted synchronous reluctance motor drive example, characterized by significant saturation and cross-saturation. State-of-the-art control techniques such as current vector control and non-model-based direct flux vector control are also considered, for the sake of comparison, in simulations and experiments.

Abstract

This paper proposes a direct flux vector control strategy with no need for regulators tuning, suitable for permanent-magnet (PM) synchronous machine drives. The controller operates in stator flux coordinates and calculates the inverter reference voltages in a model-based fashion, taking advantage of a novel equation for the explicit evaluation of the torque angle error. The inverter current and voltage limits are exploited in a parameter-independent way. The method segregates the machine parameters into a single block, to make it very easy to switch from one machine to another. Experimental results are reported for a PM-assisted synchronous reluctance motor drive example, characterized by significant saturation and cross-saturation. State-of-the-art control techniques such as current vector control and non-model-based direct flux vector control are also considered, for the sake of comparison, in simulations and experiments.
