The authors present one possible way of calculating the exact speed of an inverter-fed induction machine without mechanical devices. In addition, a simplified algorithm, applicable for drives that do not demand high dynamic speed control performance (e.g. fans and pumps), is described. The control scheme builds on the analog basic version of the direct(More)
Mobile robots should perform a growing number of tasks and react to time-critical events. Thus, the ability to interrupt a task and resume it later is crucial. While interleaved execution occurs often in robotics, existing approaches do not consider the fact that interrupting a task and resuming an interrupted task often requires intermediate steps. In this(More)
