Nonlinear Observer Design for Mechanical Systems
نویسنده
چکیده
This paper investigates the nonlinear observer design for mechanical systems, viz. nonlinear pendulum systems, undamped oscillators and Lienard systems. Explicitly, Sundarapandian’s Theorem (2002) for observer design for nonlinear systems is used to solve the problem of local exponential observer design for nonlinear pendulum systems, undamped oscillators and Lienard systems. Numerical examples and simulations of nonlinear observer design for mechanical systems are shown to illustrate the results and validate the proposed observer design for the mechanical systems addressed in this paper.
