چکیده

An anti-windup compensator is implemented for a given nominal plasma vertical controller guaranteeing global vertical stabilization of the plasma in the presence of actuactor saturation for all reference commands. The anti-windup synthesis problem is to find a nonlinear modification of the nominal linear controller that prevents vertical instability and undesirable oscillations but leaves the nominal closed loop unmodified when there is no input saturation.

Antiwindup Scheme for Plasma Shape Control with Rate and Magnitude Actuation Constraints in the DIII-D Tokamak*

The Advanced Tokamak (AT) operating mode is the principal focus of the DIII-D tokamak. In order to be prepared for the higher control demands arising in AT scenarios, current efforts are focused on the development of an integrated multivariable controller to take into account the highly coupled influences of equilibrium shape, profile, and stability control. The first step of this project is th...

Plasma vertical stabilization with actuation constraints in the DIII-D tokamak

In the advanced tokamak (AT) operating mode of the DIII-D tokamak, an integrated multivariable controller takes into account highly coupled influences of plasma equilibrium shape, profile, and stability control. Time-scale separation in the system allows a multi-loop design: the inner loop closed by the nominal vertical controller designed to control a linear exponentially unstable plant and th...

Integrated Plasma Control in Next- Generation Devices Using Diii–d Modeling and Simulation Approaches

An extensive set of software tools for integrated plasma control has been developed, validated, and applied to the DIII–D tokamak to design controllers for plasma shape and both axisymmetric and non-axisymmetric MHD instabilities [1]. The integrated plasma control approach uses validated physics models to design controllers, and confirms their performance by operating actual machine control har...

Design calculations for fast plasma position control in Korea Superconducting Tokamak Advanced Research

We present the results of fast time scale plasma control simulations for the proposed Korea Superconducting Tokamak Advanced Research (KSTAR) tokamak. Here, the fast plasma control includes stabilization of the vertical instability and rapid radial position control. As a simulation tool, we use the tokamak simulation code (TSC). We evaluate the power supply requirements for both the vertical an...

Integrated Magnetic and Kinetic Control of Advanced Tokamak Scenarios Based on Data-Driven Models

The first real-time profile control experiments integrating magnetic and kinetic variables were performed on DIII-D in view of regulating and extrapolating advanced tokamak scenarios to steady state devices and burning plasma experiments. The integrated model-based approach that was used is generic and is being developed under the framework of the International Tokamak Physics Activity for Inte...
