Chua'S Circuit Regulation Using A Nonlinear Adaptive Feedback Technique

Abolhassan Razminia, Mohammad-Ali Sadrnia
2007 Zenodo  
Since the adaptive control is used vastly in the linear systems control, here we introduce a new trend of application of adaptive method in the chaos controlling field.  ...  In this paper, we try to derive a new adaptive control scheme for Chua's circuit controlling because control of chaos is often very important in practical operations.  ...  However since our objective in this work is stabilization to zero the reference model is easily zero dynamics.  ...
