• W2181567321 abstract "Nuclear fusion is considered to be a valuable, alternative renewable energy supply. Operation of nuclear fusion plasmas is accomplished through the tokamak concept, which combines toroidal and poloidal coils to confine the plasma magnetically. Tokamak plasmas typically constitute high-order nonlinear distributed systems, which suffer from a large number of instabilities or off-normal events requiring actively controlled stabilization. As a result many fusion related control problems arise, which all demand a dedicated control approach, differing from standard feedback control to more innovative solutions. As an example of such a fusion related control problem, the active stabilization and suppression of so-called Tearing Modes (TMs) or magnetic islands in a tokamak plasma is considered. Enhanced efficiency of a tokamak, requires higher plasma beta, plasma shaping and larger devices. Higher beta operation, however, leads to the manifestation of TMs. Localized injection of electron cyclotron (EC) waves has demonstrated its feasibility to stabilize TMs. Efficient, flexible and well-localized heating and current drive by EC waves can be achieved applying a mechanical Electron Cyclotron Resonance Heating (ECRH) launcher system. The work reported primarily focuses on the mechanics and control of such a system with a 2 rotational degrees of freedom (DOF) steer-able mirror, operated at TEXTOR. The dynamics of this instrument are measured and modeled in terms of Frequency Response Function (FRF) estimation and equations of motion. Nonlinear system behavior (mainly induced by friction) is characterized and modeled. The impact of external disturbances is considered. This identification procedure allows design and implementation of a cascaded control strategy for improved actuation of the mechanical launcher and also provides information on the physical limitations of the system. The report additionally presents proposals, from a control engineering perspective, for future development of real-time TM control scenarios dedicated to the TEXTOR ECRH installation. It is clarified that modeling, experiments and simulation can be adopted to design controllers, which improve the functionality of the system in real-time feedback controlled suppression and stabilization of magnetic islands." @default.
