RESUMO

The objective of this work is to study the rotor flux vector control applied to a single-phase induction motor drive. Initially, a mathematical model of the motor will be derived. The motor equations will be transformed to the stationary reference frame so that the angular dependency due to the asymmetry of the motor variables is eliminated. Then is discussed that single-phase induction motor can be viewed as a two-phase system. A mathematical model to derive the motor parameters is presented. The next step is to analyze the rotor flux vector control, pointing out the need for a symmetry transformation of the motor parameters. Two control methods are presented: direct rotor flux control and indirect rotor flux control. Theses control methods are validated through numerical simulations. Experimental analyses making use of a digital signal processor are carried out. The results obtained show the good dynamic response when the vector control method is applied to a single-phase induction motor drive system.
