Abstract: The paper aims to develop an effective predictive current control (PCC) procedure for a sensorless five-phase induction motor (IM) drive. The proposed PCC considers the discrete behaviour of the voltage source inverter (VSI) and provides the voltage vectors utilising the finite control set (FCS) principle, thus, there is no need for using the pulse width modulation (PWM) techniques. A combined sliding mode-Luenberger observer is used to estimate the motor speed, stator current, rotor flux, load torque, and stator and rotor resistances. An effective pole placement procedure is proposed for selecting the most appropriate gains of the observer to enhance the estimation process and to improve the observer's robustness against uncertainties in the system. The drive performance has been tested for a wide range of speed changes. The obtained results demonstrate the effectiveness of proposed PCC in obtaining high dynamic performance from the drive. Moreover, the proposed sensorless procedure has confirmed its validity to estimate precisely the required control variables.
