Model Update with Observer/Kalman Filter and Genetic Algorithm Approach

The discrete time Observer/Kalman model technique is implemented in order to identify the structure pulse response. The model update procedure based on finite element model pulse response of the test structure and the genetic algorithm is developed. The objective function evaluates the difference between the system and the model pulse responses. The modal assurance criteria implementation is considered. The model reduction in order to match model degrees of freedom (dofs) and test structure dofs involved in experiment is discussed. The case study on the frame test structure is provided.
