Nonlinear observer design for chaotic systems

Abstract

This work investigates the nonlinear observer design for chaotic systems. Explicitly, we have applied Sundarapandian’s theorem (2002) for local exponential observer design for nonlinear systems to design nonlinear observers for chaotic systems with a single stable equilibrium point, viz. Wei-Wang system (2013) and Kingni-Jafari system (2014). MATLAB simulations are provided to illustrate the phase portraits and nonlinear observer design for the Wei-Wang and Kingni-Jafari chaotic systems.
