Observer for Nonlinear Systems Using Mean Value Theorem and Simulated Annealing Algorithm
Authors: ,
Abstract: In this note, we consider a new nonlinear unknown input observer design for large class nonlinear systems. The principal idea consist on using estimation error and mean value theorem parameters β in proposed observer structure, based on the feedback mechanism. This process is performed using mean value theorem and simulated annealing algorithm. A stability study was performed using classical Lyapunov function. Numerical examples are designed to show the effectiveness of the approach proposed for nonlinear dynamic systems concerned. Proposed observer can treat nonlinear systems without a linear term (x’ = f(x, u)) and with a linear term (x’ = Ax + f(x, u)).
