Control of an Active Suspension System Subject to Random Component Failures

Abstract

Two fault-tolerant control algorithms based on certainty-equivalence and dual control approximations, are described in this paper. These algorithms maintain the system performance in the presence of component failures. Their performance is demonstrated by simulations of an active suspension system subjected to sensor and actuator failures. Both algorithms provide viable solutions to the problem of faulttolerant control in automotive systems. However, the certainty-equivalence control algorithm is simpler to implement.
