摘要：
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 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 strategy operation.
