| Abstract |
We propose a compressive sensing based model predictive control scheme of three level neutral pointclamped inverters with permanent magnet synchronous machines. Therefore an inverse model of thesystem is proposed. The inverse model is then used to set up an optimization problem that yields theoptimal switching state. Contrary to the two level inverter the geometric structure of the space vectorsfor the three level inverters is not optimal for compressive sensing. For this reason we propose a modifiedspace vector selection scheme to overcome this problem that furthermore takes the neutral point voltageinto account. The framework is verified and evaluated with numerical simulations. |
