چکیده
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, RF-MRAS not guaranteed due conventional PI-based (PIA) and parameter uncertainties, especially time constant. In order improve RF-MRAS, the PIA replaced by an based on control (ISMC). ISMC design, term that contains constant considered as noise, a reference model-based approximation employed adapt Moreover, bipolar sigmoid function utilized reduce chattering-phenomenon. Simulations with direct torque IMD confirm advantages MISMCA compared in terms maximum value ITAE index estimated error. DOI: 10.61416/ceai.v25i3.8563

Abstract: In this paper, an induction machine rotor speed and rotor flux control using a sensorless backstepping control scheme is discussed. The most interesting point of this technique is that it deals with the nonlinearity of a high-order system by using the virtual control variable to make this system simple, and thus the control outputs can be derived step by step through appropriate Lyapu...

This paper proposes a new sliding mode control (SMC) based model reference adaptive system (MRAS) for sensorless indirect field oriented control (IFOC) of a single-sided linear induction motor (SLIM).
