Description
Within the preliminary developments related to the Gran Telescopio
Canarias, a test rig is being designed for the active control of the
support system of the segmented primary mirror. The construction of this
test rig will be divided in two phases: the first one will basically
consist in the implementation and testing of a displacement sensor
prototype as well as an actuator prototype. Phase 2 will consist in the
development and characterization of the whole test rig, including two
segment simulators and a number of displacement sensors and actuators.
Also, a non contact optical system for the test rig behavior
verification will be constructed during phase 2. This paper presents the
conceptual design adopted for the active control system proposed for the
telescope and a brief description of the development program, including
the requirements of the displacement sensors and actuators. We intend
the test rig not only for testing the active control system components,
but also for checking different control strategies.
