Abstract
This paper proposes a simple model predictive current control (MPCC) approach for five-phase open-windings (OW) PMSM drive. In the presented control approach, the control-set is designed by using the virtual voltage vectors (V <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sup> s) of the two voltage source inverters (VSIs), which cancel the x-y voltage components. Taking 10 V <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sup> s and zero-vector for each VSI, 121 V <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sup> s are available as a control-set for the studied system. However, only 21 voltage vectors are selected, which have zero-sequence voltage (ZSV), to remove the zero-sequence current. The best vector is chosen from the 21 candidate vectors according to the information of the reference α-β voltage vector, which is determined by the deadbeat (DB) basis. Hence, the control targets are obtained with the minimum computational load. The capability of the presented MPCC approach is examined using MATLAB simulation.
