| Abstract |
Several improvements to the vector control of induction machines are presented. Parameter identification of the rotor time constant using the extended Kalman filter (EKF) is improved by including the effects of machine core losses. This is used to improve the machine model for the vector controller - giving more accurate torque response. Triplen harmonic injection is shown to extend machine operation before field weakening occurs. Deadbanding is implemented to reduce current controlled inverter switching losses. A Motorola 96002 DSP based hardware system is used to implement these methods. |
