| Popis: | This paper addresses the design of a fault-tolerant semi-active suspension controller. The fault-tolerant properties of the controller are realized by an LPV anti-windup approach using saturation indicator scheduling parameters. The saturation indicators model the force limitations of the semi-active dampers in the LPV framework and thus allow for the synthesis of semi-active suspension controllers with guaranteed closed-loop stability and performance. Additionally, the saturation indicators readily describe damper failures like e.g. oil leakage which extends the controller validity from normal operation to faulty operation modes. This property of the saturation indicator concept is exploited by augmenting the LPV controller by a damper force reconfiguration which explores the weak input redundancy provided by four semi-active dampers. The damper force reconfiguration aims at a maximization of ride comfort performance in the presence of damper failures. The achievable ride comfort improvement is illustrated by a simulation study with a full-vehicle model excited by sine sweeps. |
