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.‎
