A conforming representation composed of two-dimensional finite elements and finite Fourier series is applied to three-dimensional nonlinear non-ideal magnetohydrodynamics using a semi-implicit time-advance. The self-adjoint semi-implicit operator and variational approach to spatial discretization are synergistic and enable simulation in the extremely stiff… (More)

Recent DIII-D experiments with reduced neutral beam torque and minimum nonaxisymmetric perturbations of the magnetic field show a significant reduction of the toroidal plasma rotation required for the stabilization of the resistive-wall mode (RWM) below the threshold values observed in experiments that apply nonaxisymmetric magnetic fields to slow the… (More)

It is found that resistive wall modes with a toroidal number n = 1 in tokamaks can be stabilized by plasma rotation at a low Mach number, with the rotation frequency being lower than the ion bounce frequency but larger than the ion and electron precession drift frequencies. The stabilization is the result of the shear-Alfvén resonance, since the thermal… (More)

In this paper, active control of space manipulator with flexible-link and flexible-joint was investigated based on the singular perturbation method. Owing to the combined effects of the link and joint flexibilities, the dynamics model of this type of manipulator became more complex and led to a series of unsolved control system. To simplify the design of… (More)

The fully self-consistent simulation of energetic particle turbulence and transport in burning plasmas such as ITER must incorporate three new physics elements: (i) kinetic effects of thermal particles at the thermal ion gyroradius (micro scale), (ii) nonlinear interactions of many meso scale (energetic particle gyroradius) shear Alfvén waves induced by the… (More)

This paper describes the results of an analysis conducted to quantify and determine how applications/services deployed using an IMS infrastructure can reduce operations costs and improve "time to market (TTM)". A detailed task-based operations cost model was developed for comparing IMS-based solutions with point solutions. The model used the following:… (More)

Based on the energy-saving gearshift law of the technical vehicles. a fundamental of the shift control was established. By using fuzzy control theory, a fuzzy shift scheme was developed in this paper to realize the automation of the manipulating. The strategy is composed of a fuzzy shift strategy, which sets the schedule according to the rotating speed… (More)
