Abstract

The two-phase induction motor (TPIM) is deliberated as a variable speed motor for home applications owing to progressing of power electronics. Three-leg voltage source inverter (VSI) is used for driving the TPIM. Switching states of the three-leg VSI can be obtained by current control. Current control technique is used to regulate the stator currents of TPIM. This paper provides two different current control techniques for the three-leg VSI. First, the hysteresis current controller (HCC) is used for the stator current regulation in synchronous reference frame. Second, the finite control set-model predictive controller (FCS-MPC) has been investigated to control the stator current in stationary frame. A proposed mathematical model for TPIM has been investigated to be used for FCS-MPC. The motor performance under current control techniques has been established through MATLAB/SIMULINK. The results demonstrate the effectiveness of the mathematical model beside performance enhancement of the TPIM under FCS-MPC based on reducing torque ripple and switching frequency.
