Measurement of the open loop plasma equilibrium response in TCV (2008)

Coutlis, A., Bandyopadhyay, I., Lister, J. B., Vyas, P., Albanese, R., Limebeer, D. J. N., ...

A new technique and results are presented for the estimation of the open loop frequency response of the plasma on TCV. Voltages were applied to poloidal field coils and the resulting plasma current,...

Frequency response identification of the dynamics of a Tokamak plasma (2008)

Coutlis, A., Limebeer, D. J. N., Wainwright, J. P., Lister, J. B., Vyas, P.

In this paper we describe the application of an H-infinity system identification procedure to a Tokamak. The work is motivated by the need to create linear models which are suitable for controller...

Linear and non-linear plasma equilibrium responses on the JT-60U and TCV tokamaks (2008)

Lister, J. B., Khayrutdinov, R., Limebeer, D. J. N., Lukash, V., Nakamura, Y., Sharma, A., ...

Although linear response models are useful for feedback controller design, their linear time-invariant properties cannot simulate the evolution of a full plasma discharge. A suitable code for this...

Comparing DINA code simulations with TCV experimental plasma equilibrium responses (2008)

Khayrutdinov, R. R., Lister, J. B., Lukash, V. E., Wainwright, J. P.

The DINA nonlinear time-dependent simulation code has been validated against an extensive set of plasma equilibrium response experiments carried out on the TCV tokamak. Limited and diverted plasmas...

Plasma equilibrium response modelling and validation on JT-60U (2008)

Lister, J. B., Sharma, A., Limebeer, D. J. N., Nakamura, Y., Wainwright, J. P., Yoshino, R.

A systematic procedure to identify the plasma equilibrium response to the poloidal field coil voltages has been applied to the JT-60U tokamak. The required response was predicted with a high accuracy...
