This work proposes a direct torque control with space vector modulation based on load angle using PI controllers. This controller calculates dynamically the load angle between stator and rotor flux vectors using a PI controller. A reference of stator flux on stationary reference frame is calculated by using the load angle, rotor position and the stator flux magnitude. Another PI controller calculates the stator voltage to be supplied to the induction motor based on stator flux error. Thus, the electromagnetic torque necessary to supply the motor load is achieved. This strategy is easy to implement and experimental results are presented to validate the proposed strategy.899309313Takahashi, I., Noguchi, T., A New Quick-Response and High-Efficiency Control Strategy of an Induction Motor (1986) Industry Applications, IEEE Transactions on, (5), pp. 820-827. , SeptDepenbrock, M., Direct self-control (DSC) of inverter-fed induction machine (1988) Power Electronics, IEEE Transactions on, 3 (4), pp. 420-429. , OctHabetler, T.G., Profumo, F., Pastorelli, M., Tolbert, L.M., Direct torque control of induction machines using space vector modulation (1992) Industry Applications, IEEE Transactions on, 28 (5), pp. 1045-1053. , Sep/OctKang, J.-K., Sul, S.-K., New Direct Torque Control of Induction Motor for Minimum Torque Ripple and Constant Switching Frequency (1999) Industry Applications, IEEE Transactions on, 35 (5), pp. 1076-1082. , Sep/OctStojic, D.M., Vukosavic, N., Slobodan, A New Induction Motor Drive Based on the Flux Vector Acceleration Method (2005) Industry Applications, IEEE Transactions on, 20 (1), pp. 173-180. , MarchLee, J.H., Kim, C.G., Youn, M.J., A deadbeat type digital controller for the direct torque control of an induction motor (2002) Power Electronics, IEEE Transactions on, 17 (1), pp. 739-746. , SeptemberLascu, C., Boldea, I., Blaabjerg, F., Direct torque control of sensorless induction motor drives: A sliding mode approach (2004) Industry Applications, IEEE Transactions on, 40 (2), pp. 582-590. , MarchBeerten, J., Verveckken, J., Driesen, J.L.J., Predictive Direct Torque Control for Flux and Torque Ripple Reduction (2010) Industrial Electronics, IEEE Transactions on, 57 (1), pp. 404-412. , JanuaryThomas, J., Hansson, A., Speed Tracking of a Linear Induction Motor-Enumerative Nonlinear Model Predictive Control (2012) Control Systems Technology, IEEE Transactions on, 20. , JanuaryChen, L., Fang, K.-L., Hu, Z.-F., A scheme of fuzzy direct torque control for induction machine (2005) Machine Learning and Cybernetics, 2, pp. 803-807. , 18-21 Aug. 2005Koutsogiannis, Z., Adamidis, G., Fyntanakis, A., Direct torque control using space vector modulation and dynamic performance of the drive, via a fuzzy logic controller for speed regulation (2007) Power Electronics and Applications, pp. 1-10. , 2-5 Sept. 2007Abu-Rub, H., Guzinski, J., Krzeminski, Z., Toliyat, H.A., Advanced control of induction motor based on load angle estimation (2004) Industrial Electronics, IEEE Transactions on, 51 (1), pp. 5-14. , FebRodriguez, J., Pontt, J., Silva, C., Kouro, S., Miranda, H., A Novel Direct Torque Control Scheme for Induction Machines with Space Vector Modulation (2004) 35th Annual IEEE Power Electronics Specialists ConferenceVas, P., (1998) Sensorless vector and Direct Torque Control, , Oxford University PressHu, J., Wu, B., New integration algorithms for estimating motor flux over a wide speed range (1998) Power Electronics, IEEE Transactions on, 13 (5
