this paper presents a sensorless system drive on primary flux oriented control (pfoc) and secondary flux oriented control (sfoc) for the linear induction motor (lim) with taking into account end effect. extended kalman filter (ekf) is applied to estimate lim speed by measuring motor voltages and currents. in order to achieve desirable dynamic and robustness motor performance instead of traditio...

in this paper, a new field oriented control scheme with maximum torque for permanent magnet hysteresis synchronous (pmhs) motor has been presented. vector control method provides significant improvement to the dynamic performance of ac motors but in this method d- axis current is controlled such as the ratio of motor torque to motor current is a maximum, then the dynamic performance will be ver...

We examine the effectiveness of the individual-punishment mechanism in larger groups, comparing groups of four to groups of 40 participants. We find that the individual punishment mechanism is remarkably robust when the marginal per capita return (MPCR), i.e. the return to each participant from each dollar that is contributed, is held constant. Moreover, the efficiency gains from the punishment...
