| Abstract |
This paper proposes a new robust approach to Direct Torque Control (DTC)
of induction machines based on the use of a robust Kalman filter. In the continuous time direct torque scheme proposed, a state feedback (DTC) control law is combined with a
robust Kalman filter which provides robust estimates of the rotor and stator fluxes. The robust Kalman filter is designed to be robust with respect to variations in the rotor and stator resistances. Simulation results show that the resulting robust DTC controller is considerably more robust with respect to rotor and stator resistance variations than the standard DTC controller. These simulation results are verified by experimental results in which the proposed robust DTC control scheme is applied to a 2.2kW machine. |
