Abstract
Automation of some tasks requires the speed control of dc motors, this also requires a speed observer. In this work it is described a method that combines two sensorless speed techniques for speed estimation without sensors, one of them is based on the dynamic motor model and the other one is based in the ripple component. It is also evaluated the improvement introduced by combining both techniques using as reference the accuracy provided by a method based only on the ripple component. The results clearly show, that the method based on both sensorless speed techniques provides important improvements in the detection of the speed, when the speed is small or when it is changing.
