The Fault Modeling Methodology of Actuator System Based on Modelica
The multi-domain model established based on Modelica can effectively describe the dynamics and randomicity of failure behavior in complex systems. Firstly, the characteristics of multi-domain model are described, and the modeling methodology of failure behavior in complex systems based on multi-domain language is introduced; then the multi-domain model of actuator is established based on the components behavioral model library; finally, the actuator system is simulated and results are analyzed. The results show that not only the dynamic failure behaviors of complex systems, transfer process of different behaviors and performance fluctuations caused by failure behavior, but also the stochastic time when fault happens and uncertainty of parameters can be described by the proposed modeling methodology. It is validated that the methodology is useful for engineering application.
