Abstract :
With increasing system complexity and extensive use of computerized control of industrial processes and plants, it is essential to have a systematic approach for identifying failures that can expose people and environment for unacceptable risks. With focus on a drive system used to control a linear motor, the fault tree analysis method is utilized to reveal design weaknesses and to find mitigations that can improve the system safety characteristics. Starting with a set of top level hazards, elements with high risk impact are identified, and appropriate mitigations are suggested.
