This Letter presents a novel modeless predictive current control (PCC) based on two vectors for a synchronous reluctance motor (SynRM) drive system fed by a four‐switch three‐phase (FSTP) inverter. In each sampling period, two voltage vectors generated by the FSTP inverter are applied to emulate the operation of a six‐switch three‐phase inverter. Unlike model‐based approaches, the proposed method is modeless, meaning that it does not require a system model or its parameters nor the capacitor voltage. For comparison purpose, both model‐based and modeless PCCs are realised on a FSTP inverter‐fed SynRM drive system via a 32‐bit digital signal controller to contrast their current‐tracking performances.
