摘要
After an introductory part in issue 4/2007 this part 2 then considers some examples of realized fault-tolerant systems as, e. g., a fault tolerant position sensor for an electrical throttle actuator, a fault-tolerant asynchronous drive with different duplex configurations, and the analytical sensor redundancy for the lateral dynamic behaviour of a passenger car. The applied fault-detection methods and the reconfiguration strategy are described. Herewith it is shown how the function can be maintained with only small disturbances of the operation after appearance of faults.
