Resumen:
This work presents a dead-time compensation technique for robust predictive current control of grid-connected voltage source inverter. Among current controls, dead-beat predictive controllers are one of the fastest, but are extremely sensitive to inconsistencies between the model and the actual plant. Dead-time modifies the plant model and is one of the main sources of distortion in high dynamic range inverters, so it is necessary to include it in the model in order to mitigate its effect. Therefore robust and adaptive predictive current control with non-linear gain scheduling is proposed to compensate dead-time effect.
