The traditional irrigation meter controller carries on the sampling to the outlet pressure of main pipe in the pipe network and adopts the traditional PID to control water pressure. The effect is not very good by this means...
In this paper, a new efficiency-optimized space-vector-modulation direct torque control (DTC) scheme is proposed and implemented for induction motor drives. Different from the traditional DTC, in which the flux linkage reference value is set as the rated value, the flux linkage reference value in the proposed DTC is online updated according to the instantaneous load torque and rotational speed by...
