Identification and control techniques for real-time hybrid simulations

Course objective 
The scope of the course is to provide knowledge of identification and experimental techniques used to  characterize the hysteretic behaviour of mechanical/structural systems subjected to dynamic/earthquake loading. Some numerical methods and elements of advanced identification and control exploited in modern mechanical engineering are proposed.

 

Who should attend

Graduate students in engineering interested in linear/non-linear structural dynamics and control, and researchers, in modern mechanical/structural engineering.

 

Course outine

Fundamentals of system identification and applications to mechanical/civil structures. Fundamentals of vibrationbased structural health monitoring. Concepts of signal analysis. Experimental modal analysis. Identification in frequency, time and time-frequency domain.
