Torque and speed sensorless induction motor control is presented in this paper. The idea is realized using a sliding mode closed loop rotor flux observer for estimation of electromotive force of machine. This signal is then used in nonlinear stator flux and torque control of induction motor and in rotor flux observer for speed and flux estimation. The analysis of the proposed method is included...

We present a new system for the automatic determination of the position , size and pose of the head of a human gure in a camera image. The system is an extension of the well{known face recognition system WFK] to pose estimation. The pose estimation system is characterized by a certain reliability and speed. We improve this performance and speed with the help of statistical estimation methods. I...

Typically, the rotor speed of electric motors was measured directly by use electromechanical sensors. Even though these devices are very precise, they also fragile and expensive to install. Currently, some alternatives based on estimations from measurement stator currents. Some these, accurate, used in variable drives. In industrial power applications, many large induction (IMs) driven with spe...

We describe a layered evaluation approach to assess the accuracy of traffic speed estimation based on floating phone data. We designed a simulation framework to investigate the influence of various parameters on the estimation. Multiple quality metrics and combinations of metrics have been used and intervals of metric values have been mapped to quality ratings to enable a uniform and comprehens...
