Three-phase induction motors have been widely used in industry. In addition, sensorless speed electric drive systems are more and more popular as they have small sizes, low-costs, high reliability and suitable with novel robust control algorithms. In these drive systems, the speed measuring devices with tachometers or photoelectric encoders have been replaced by sensorless estimation algorithms. This paper describes a method of sensorless speed estimation of three-phase induction motor based on MRAS and Fuzzy logic controller. The simulation results obtained show that the estimated motor speed tracks the actual motor speed with very small error.
