Abstract

A highly reliable fault tolerant microprocessor-based governor with high performance is being developed. In this system, techniques such as redundancy, fault detection, fault location, fault isolation, and self-recovery have been applied successfully to achieve high reliability. The hardware architecture of this system and its fault tolerance aspects are described. The software structure and the redundancy architecture are presented. The fault detection, the fault location, and the fault isolation techniques applied to this system are studied. The self-recovery and reconfiguration of the system and the switch-over control based on the fault detection results are discussed
