Modelling and robust control design of a standalone wind-based energy storage generation unit powering an induction motorvariable-displacement pressurecompensated pump

2018-09-02 10:38:43 Keywords sliding mode control, , induction motor drive, sliding mode control, , wind,
Modelling and robust control design of a standalone wind-based energy storage generation unit powering an induction motorvariable-displacement pressurecompensated pump
This study investigates the application of the sliding mode controller (SMC) for induction motor drive variable-displacement pressure-compensated pump (VDPC) system powered by an isolated wind/storage unit. The variable-speed wind turbine (WT) is proposed to drive a permanent magnet synchronous generator (PMSG) which, feeds a storing energy unit and stand-alone dynamic load. Energy storage systems are required for power balance quality ... Read more

Deteriorating effects of the metal threads on embroideries
Embroideries are considered one of the most important complex textiles which are distinguished with a raised pattern by using additional threads called extra yarns. They are generally thicker than the original warp and weft threads. Usually, they are made of metal threads. These metal threads are made of gold, silver, copper and/or their alloys as well as gilt and silvered ... Read more
