Abstract :
This work deals with the self-calibration of a high-precision open-loop mechanism. The method is applied to a mechanical shutter for space application, which will be launched onboard the ROSETTA mission (launch time: February 2004). It is based on an adaptive ´model reference´ and a ´randomized´ search method that can be generalized to applications where high performances and functionality have strong interconnections.
