Abstract: This article proposes a novel low-voltage ride-through (LVRT) control strategy for doubly-fed variable-speed pumped hydro storage (VS-PHS) units. Unlike conventional LVRT approaches for ...

Abstract: In this paper, a finite-time variable gain control method is proposed to address noise and disturbances in active suspension hydraulic systems (ASHS). The proposed method integrates ...

Economics often borrows ideas from the sciences, yet unlike physics or chemistry, no country has ever run a controlled, pure economic experiment on a national scale. A pure experiment requires ...

Choose the VFD control mode based on the ratio of the system pressure to maximum internal pump pressure. For a centrifugal pump delivering to a system with high operating pressure and or high static ...

United Nations Command, U.S. Forces Korea, and Combined Forces Command commander Gen. Xavier T. Brunson (2nd from left) talks to a Korean War veteran at a ceremony in South Korea to commemorate the ...

Why get up close and personal with a resistor when you can tweak it from a distance? Remote variable resistors make analog circuit control easier, neater, and a lot more fun. Well, we are about to ...

Background: Short video addiction has become increasingly prevalent among college students. It can negatively impact their physical and mental health, yet its influencing factors and underlying ...

In today’s world, motors are ubiquitous, powering everything from household appliances to industrial machinery. The importance of optimizing motor control for energy efficiency cannot be overstated, ...
