Extension of the tuning constant in the Huber's function for robustn modeling of piezoelectric systems

摘要

This paper proposes a new modeling approach that is experimentally validated on piezoelectric systems in order to provide a black-box pseudolinear model for complex systems control. Most of the time, one uses physical based approaches. However, sometimes complex phenomena occur in the system due to atypical changes of the process behavior, output noise or some hard nonlinearities. Therefore, we adopt identification methods to achieve the modeling task. The microdisplacements of the piezoelectric
