Abstract : This paper presents an approach to control the remaining useful lifetime (RUL) of a friction drive system. The approach is based on the assumption that the system deterioration is a consequence of the motion control actions. These control actions have short-term objectives that have to be modified, based on the predicted RUL, to be compatible with the required/desired RUL. Here, a RUL actuating principle is proposed in order to control the RUL. That actuating principle is based on a parametric varying filter which modifies the motion control realization based on the available information about the expected RUL. The total RUL control architecture also includes an operating condition estimator, a system state estimator, and a RUL predictor. The RUL controller determines the parameters of the actuating filter by solving an on-line optimization problem. The RUL controller has to solve the RUL control problem by considering a trade-off between the desired motion control actions and the desired RUL. A numerical example illustrates the behavior of the proposed control architecture.
