  • Abstract
    In this study we propose an estimator for detecting impacts during the evolution of linear systems subject to unilateral constraint with only the measurement of the position (possibly corrupted by noise). The detection scheme is based on fast algebraic estimator methods. This work provides an estimator, which is independent to the knowledge of the constraint position. Some simulation results are given in the presence of noise.
