Application of the model predictive control and the SVPWM techniques on five-phase inverter
The multi-phase inverters have attracted recently much attention among the researchers, practitioners and industries due to their many advantages compared to their conventional count parts of single and three-phase inverters, which have been used widely in almost the domestic, commercial and industrial application. The present paper presents an invitation on the application of the space vector pulse width modulation (SVPWM) control technique and the model predictive control (MPC) technique on a five-phase inverter powering a star connected five-phase load. Firstly, the principle of each control technique has been presented in details, then two simulation experiments have been performed on five-phase two-level inverter feeding a balanced star five-phase RL load using the SVPWM control technique and the MPC control technique separately, where a load change is considered in this two tests. The main aim from this study is to discover the main pros and cons of each control technique and their applicability in ensuring the control of five-phase inverter under different operation constraints or conditions. The obtained results for the both cases are presented and discussed based on the main key factors such as the harmonics content, the THD, the dynamic response to the load variation, the dynamic behaviours at transient situation and the computing requirement. It can be said that the present comparative study has allowed shedding the light on the main features and requirements of the applicability of the both control techniques with multi-phase inverters, which are depending on the requirement of the related application and the merits of each control technique.
