| Sumario: | The present thesis is focused on the control of three-phase power converters using sliding-mode control (SMC) in abc frame. This work has been based on previous publications about the SMC applied to three-phase power converters. The main contribution of this Thesis is the deduction of different power converter models in order to be used in a Kalman filter (KF) algorithm. The main contribution is the deduction of a model for each power converter to be used in a Kalman filter. This proposal will allow to achieve a perfect decoupling between controllers in a more efficient way compared with the methods proposed in the state-of-the-art. It must be highlighted that the system behaviour can be modified according to the selected model which modifies the closed-loop dynamics according to some specific requirements, for instance to achieve active damping in voltage source inverters with LCL filter. In addition, the use of this estimator allows to obtain the PCC voltages free of noise and distortion even in the case of a highly distorted grid. The converters presented in this manuscript are a Voltage source inverter with LCL filter, a three-phase unity power factor rectifier and a three-phase active power filter. |
