New Results of the Development and Application of Robust Observers

  • Dirk Söffker
Part of the Solid Mechanics and its Applications book series (SMIA, volume 130)


This contribution deals with a model-based approach for fault detection and vibration control of elastic mechanical structures. Especially in the case of lightweighted structures, online and in-situ fault diagnosis becomes important due to internal delamination processes of modern CFK-materials. Additionally faults like cracks or impacts acting on a flexible structure has to be observed. Structural-Health-Monitoring (SHM) concepts deal with different tools to realize safe adaptronic structures, realizing fault monitoring and repair mechanism in combination with intelligent monitoring of the hazard rate of the complete structural integrity.

Core of the contribution are new results of the development and application of the robust PI-Observer. Due to the fact that the lifetime of modern actuators (piezoelectric or shape-memory-alloy based) strongly depends on the use intensity safety aspects become more and more relevant. Here briefly the SRCE-concept will be declared.
