Set-invariance analysis for deterioration prediction on a roller-on-tire actuator

Résumé

The paper deals with the problem of predicting deterioration of a roller-on-tire actuator in presence of un-predictable but bounded motor torques. Set-invariance is used to characterize the nominal behavior of the actuator and the maximal admissible deterioration behavior. A novel index of deterioration is presented and allows to model the mechanical actuator as a polytopic Linear Parameter Varying model. For a given initial deterioration, the probabilistic certification approach is used to numerically predict an interval of “expected time” for reaching the total outage of the actuator. A simulated example illustrates the interest of the proposed approach and its potential integration on future predictive maintenance techniques.
