In a typical quadruplex actuator system, how is the failure of an actuator identified? 1) By comparing it with the signal of the three good ones 2) By comparing it with a simulation model 3) Using in-lane fault detection 4) Using reflectometry
Answer: By comparing it with the signal of the three good ones Explanation: A typical quadruplex system uses signal processing based FDI( Fault Detection and Isolation) system. It identifies the failed actuator by comparing its control signal with the other three good ones. A model-based FDI system is generally used in triplex architecture.
