When actuators are requested to be disabled or slaved, control matrices have to be re-computed. The report describes the algorithms to re-compute the relevant matrixes for controlling of the mirror without the need of recalibration. This is related in particular to MMT, LBT, Magellan, VLT, ELT and GMT adaptive mirrors that use the voice-coil technology. The technique is successfully used in practice with LBT adaptive secondary mirror units. | URI: | http://hdl.handle.net/20.500.12386/29767 http://dx.doi.org/10.20371/INAF/TechRep/68 |
