After nearly a century of industrial use, the PID controller remains the workhorse of process automation. It regulates ...

Due to their versatility, ease of design, and low cost, flyback converters have become one of the most widely used topologies in power electronics. Its structure derives from one of the three basic ...

The authors developed a methodology to graph antigenic surface loops on influenza virus neuraminidases. The hybrid proteins retained the structure of the neuraminidase scaffold and the antigenicity of ...

The performance of a modular multilevel converter (MMC) is highly related to the three-phase phase-locked loop (PLL). The presence of the DC component, the harmonic component, and the negative ...

In the past couple of years, zero-field optically pumped atomic magnetometers (OPMs), especially those operating in the spin-exchange relaxation-free (SERF) regime, have been developed rapidly and ...

Abstract: Converter-grid interaction is of great interest in a weak-grid condition. This paper presents a single-input-single-output (SISO) open-loop transfer function for the stability analysis of ...

Abstract: The stability margin is an important attribute for the robustness analysis of the closed loop in a control system design, which indicates the tolerant-ability of the closed-loop stability to ...

The two most common categories of process responses in industrial manufacturing processes are self-regulating and integrating. A self-regulating process response to a step input change is ...

Today’s electronic systems are becoming more and more complex, with an increasing number of power rails and supplies. To achieve optimum power solution density, reliability and cost, often system ...
