Abstract

In this study, we describe a model based fault tolerant control method for steer-by-wire system. First of all general redundancy schemes and current works for steer-by-wire fault tolerant control systems are examined. Then the paper focuses on the fault tolerant control methods of key sensors and DC motors for steer-by-wire system. With the aim to provide a steady and reliable fault tolerant control algorithm we synthesize Adaptive Fading Kalman Filter and fault eigenvectors as a framework to establish the fault tolerant control system. The effectiveness of this research is demonstrated by simulation. Finally key innovations of the fault tolerant control method are discussed.
