Samenvatting

This paper discusses several relevant control aspects, regarding the specific task of feedback-controlled stabilization of Neoclassical Tearing Modes (NTMs), for the Electron Cyclotron Resonance Heating (ECRH) installation operated at TEXTOR. The work reported primarily focuses on the mechanics and control of an ECRH launcher system with a 2 rotational degrees of freedom (DOF) steer-able mirror. The dynamics of this instrument are measured and modeled in terms of the equations of motion. Nonlinear system behavior (mainly induced by friction) is characterized. The impact of external disturbances is considered. This system 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 paper additionally presents a proposal, from a control engineering perspective, for development of NTM control scenarios, dedicated to the TEXTOR ECRH installation.
