Abstract
- This study presents a finite-control-set model predictive current control (FCS-MPCC) with phase shift compensation for a cost-effective voltage source inverter. Firstly, the FCS-MPCC algorithm uses the discrete-time model of the inverter to predict the coming value of the load current. In addition, a cost function is defined to evaluate all possible voltage vectors from the inverter, where the cost function is selected. Moreover, a pulse computation module is developed to obtain the final switching signals for insulated-gate bipolar transistors. In addition, the problem of current distortion caused by phase shift is solved by employing a time interval compensation factor. Furthermore, a comparison between the hysteresis control, pulse-width modulation control, and proposed predictive control is presented in terms of the steady-state and dynamic performances. Both simulation and experiment are conducted, which confirm the validity of the proposed control scheme of FCS-MPCC. [ABSTRACT FROM AUTHOR]
