Efficiency trends in electric machines and drives ¬リニ

Almost all electricity in the UK is generated by rotating electrical generators, and approximately half of it is used to drive electrical motors. This means that efficiency improvements to electrical machines can have a very large impact on energy consumption. The key challenges to increased efficiency in systems driven by electrical machines lie in three areas: to extend the application of var...

Applications of ripple correlation control of electric machinery - Electric Machines and Drives Conference, 2003. IEMDC'03. IEEE International

Abshacr Ripple correlation control can be applied to electric dr*e system in order to optimize some cost function independent of parameters. Tbis involves correlating the perturbations in the cost function with the perturbations in the independent variable to obtaim a command for the independent variable. The perturbations are normally due to ripple that is naturally prewnt in electric drive sy...

Observability of Sensorless Electric Drives

Electric drives control without shaft sensors has been an active research topic for almost three decades. It consists of estimating the rotor speed and/or position from the currents and voltages measurement. This paper deals with the observability conditions of electric drives in view of sensorless control. The models of such systems are strongly nonlinear. For this reason, a local observabilit...

Motion Control for Electric Drives

This paper present a general overview of the motion control system blocks, specially that related with motor considerations and torque control. Moreover, some trends in motor control systems are also presented.
