Modeling nonlinear scattering processes on antennas with a nonlinear load

Antennas
To determine the amplitude, spatial and frequency properties of nonlinear scattering on antennas with a nonlinear load, it has been proposed to measure or calculate three dependencies: the amplitude characteristic (the dependence of the intensity of the electromagnetic wave scattered on harmonics on the intensity of the irradiating wave of the probing ...

Nonlinear fuzzy logic control of a PWM inverter with a nonlinear load

PowerCon 2000. 2000 International Conference on Power System Technology. Proceedings (Cat. No.00EX409), 2002
Capacitor input filter loads (nonlinear) typically cause voltage distortion in DC to AC inverter waveshape. Nonlinear fuzzy logic control fields promise in reducing this compared with conventional PID control. Comparisons between nonlinear fuzzy logic proportional derivative controllers and conventional linear PID controllers are made by simulating a ...

Nonlinear control for AC/DC power system with nonlinear loads

2004 International Conference on Power System Technology, 2004. PowerCon 2004., 2005
In view of the nonlinearity of loads and HVDC in power systems, the M derivative, M bracket and MIMO feedback linearization based on nonlinear differential algebraic system (NDAS) are introduced into the design of nonlinear controller for parallel AC/DC power system.

Nonlinear load exceedance model for cyclic load processes: development

Structural Safety, 1999
Studies of structural response due to stochastic load processes have been extended to include nonlinear material response. The studies on the Poisson processes with rectangular pulses were for positive pulse intensity such as gravity load. The reliability analysis developed was not applicable for processes with reversible cyclic load pulses such as ...

Traveling Loads on Viscoelastic Plates on Nonlinear Foundations

Journal of Applied Mechanics, 1977
Within the framework of Kirchhoff-type prestressed plate theory, the steady-state response of a viscoelastic plate strip on a nonlinear dissipative foundation to the action of general traveling loads is considered. Since an hereditary integral-type viscoelastic constitutive model is employed, the governing field equation is of the nonlinear ...

Nonlinear Analysis of Intervertebral Disk Under Dynamic Load

Journal of Biomechanical Engineering, 1990
This study pertains to the response of intervertebral joint under dynamic axial load. The numerical model represents two vertebral bodies with an interposed disk and uses three-dimensional elements. A transversely isotropic material law is adopted for cortical bone and an isotropic law for cancellous bone.

Analysis of antennas and scatterers with nonlinear loads

IEEE Transactions on Antennas and Propagation, 1976
Two methods for analyzing antennas or scatterers having nonlinear resistive loads are discussed. The first is a direct time-domain integral equation approach, whereas the second involves the use of frequency domain data to compute the time-dependent currents and voltages across the nonlinear load.

Nonlinear load characteristics of HVDC converters

12th IET International Conference on AC and DC Power Transmission (ACDC 2016), 2016
The voltage dependence of HVDC (High Voltage Direct Current) converters as a load in ac systems is studied in this paper. Analytical studies are conducted for various HVDC control modes. It is shown that HVDC converter behaves between constant power and constant current. Its reactive power is more close to constant current type load.

A nonlinear load simulator for robot manipulators

IECON'01. 27th Annual Conference of the IEEE Industrial Electronics Society (Cat. No.37243), 2002
This study is on the development of a Hardware-In-the-Loop system for the high performance control of a 2-link direct drive planar arm. At this stage of the study, necessary hardware and software has been set-up and the actual torque components derived through Euler-Lagrange formulation have been simulated in real time on the test-bed, incorporating a ...
