    Linear and Nonlinear Schemes Applied to Pitch Control of Wind Turbines by Hua Geng, Geng Yang

    Published 2014-01-01
    “…Linear controllers have been employed in industrial applications for many years, but sometimes they are noneffective on the system with nonlinear characteristics. This paper discusses the structure, performance, implementation cost, advantages, and disadvantages of different linear and nonlinear schemes applied to the pitch control of the wind energy conversion systems (WECSs). …”

    Nonlinear Stability of the Bipolar Navier-Stokes-Poisson System with Boundary by Tiantian Yu, Yong Li

    Published 2023-01-01
    “…The combined quasineutral and zero-viscosity limits of the bipolar Navier-Stokes-Poisson system with boundary are rigorously proved by establishing the nonlinear stability of the approximate solutions. Based on the conormal energy estimates, we showed that the solutions for the original system converge strongly in H3 space towards the solutions of the one-fluid compressible Euler system as long as the amplitude of the boundary layers is small enough.…”

    X-Parameter Measurement of Pulse-Compression Nonlinear Transmission Lines by Ming Li, Rony E. Amaya, Robert G. Harrison, N. Garry Tarr

    Published 2010-01-01
    “…This paper introduces a new X-parameter application: measuring large-signal behaviour of pulse-compression nonlinear transmission lines (NLTLs). A specially configured Nonlinear Vector Network Analyzer (NVNA) was used to measure the X-parameters in the frequency-domain, and then the measured data was transformed into a nonlinear time-domain waveform. …”
