Model predictive control for single phase induction motor.
The model-based predictive control method has been an important alternative to control three-phase induction motors, due to its parametric robustness and stability in transient and steady state regimes. As the absence of studies about predictive control applied to single-phase motors was observed, in this research the approached to the application of this control method is carried out with a careful analysis of the results obtained. Firstly, the main control methods are described. Then, the mathematical model of the single-phase motor used for the computational simulations is presented. The mathematic model of the predictive control for single-phase motors was developed based on the model used to control three-phase motors, but modifications were made to the model equations due to the fact that the single-phase motor windings are asymmetric. Computational simulations were performed in order to obtain information about time response, system stability and the behavior in the transient and steady state regimes. The results obtained are presented for evaluation and validation of the proposal, together with the analysis of the total harmonic distortion of the stator current.
