Abstract
We present the design and analysis of a Hyrbid controller
for the METIS Cold Chopper (MCC). The MCC is a 2D rotatable
mirror in the optical path of the Mid-Infrared E-ELT
Imager and Spectrograph (METIS) instrument [1]. It provides
telescope beam chopping by rotating this internal mirror.
The system has three degrees of freedom, two rotational
and one parasitic translational movement in the direction of
the mirror vertex. It has to satisfy stringent performance requirements
while dealing with different noise sources, disturbances
and constraints on the input signals
