چکیده مقاله :
Induction motors have become popular in the home appliance and industry due to their advantages over other motors . These motors require drives for control . The use of sensorless drive for induction motors is expanding due to its advantages. The advantages of sensorless motor drives include increased reliability, reduced hardware complexity, lower cost ,better noise immunity, and less maintenance requirements. With the advancement of industry and the development of modern industry, more efficient and advanced methods are required for sensorless control of induction motors. In this paper, sensorless control methods for induction motors are introduced and their operation and performance in different modes are investigated. The advantages and superiority of each method over other methods are examined and the simulation forms of the new model reference adaptive system (MRAS) and Classical rotor flux MRAS speed observer methods are given and these two methods are compared with other methods.
