This paper describes a model-reference adaptive system (MRAS) for the estimation of induction motor speed from measured terminal voltages and currents. The estimated speed is used as feedback in a vector control system, thus achieving moderate bandwidth speed control without the use of shaft-mounted transducers. This technique is less complex and more stable than previous MRAS tacholess drives. It has been implemented on a 30-hp laboratory drive, where its effectiveness has been verified.
