Abstract
A modified integral sliding mode control-based adaptation algorithm (MISMCA) is described to enhance performance of sensorless rotor flux model-reference-adaptive-system (RF-MRAS) induction motor drive (IMD). At low speed regions, performance of RF-MRAS is not guaranteed due to conventional PI-based adaptation algorithm (PIA) and parameter uncertainties, especially rotor time constant. In order to improve performance of RF-MRAS, the PIA is replaced by an algorithm based on integral sliding mode control (ISMC). In the ISMC design, the term that contains rotor time constant is considered as noise, and a reference model-based approximation is employed to adapt rotor time constant. Moreover, bipolar sigmoid function is utilized to reduce chattering-phenomenon. Simulations with sensorless RF-MRAS direct torque control IMD confirm the advantages of the MISMCA compared with the PIA in terms of maximum value and ITAE index of estimated speed error.
