dc.description.abstractIn this study, the design of the adaptive extended Kalman filter (AEKF) based direct torque controlled drive system with constant switching frequency (DTCD-CSF) is performed for speed-sensorless control of induction motor (IM). The system noise covariance matrix, which directly affects the estimation performance of EKFs and is assumed as constant in conventional EKFs, is updated online according to the operating conditions by the AEKF, which uses stator flux-based IM model. The reason why the proposed algorithm is included on a DTCD-CSF, instead of a conventional DTCD, is to reduce the torque ripples in the traditional direct torque control and the switching losses caused by the variable switching frequency. The load torque and the stator stationary axis components of stator currents in addition to the stator stationary axis components of stator fluxes and the rotor mechanical speed required for the DTCD-CSF are estimated by the proposed AEKF-based observer. By the load torque estimation, it is ensured that the proposed speed-sensorless drive system is robust to changes in load torque. Finally, the proposed AEKF-based speed-sensorless DTCD-CSF is verified under simulation studies.
