Popis: |
In this paper current control of two leg three phase Neutral Point Clamped (NPC) inverter feeding a resistance and inductance (RL) load using Model Predictive Control (MPC) method is presented. In this method decoupled currents are predicted using discretized load current equations obtained from application of Kirchhoffs voltage law. A cost function which is dependent on decoupled predicted currents and reference currents is evaluated for all the possible nine switching states of two leg NPC inverter. Switching state which gives minimum cost function is applied in the next sampling instant to the two-leg NPC inverter. The inverter and load are modeled using Simulink. MPC algorithm is coded in embedded MATLAB function. Simulation results confirm capability of algorithm to track reference and step change in reference currents. |
