The existence of the exponentially stable limit cycle for a class of nonlinear systems

In this paper, the exponentially stable limit cycle phenomenon for a class of nonlinear systems is investigated. Based on the analytic method, the existence and uniqueness of the exponentially stable limit cycle for such systems can be guaranteed. Moreover, the amplitude of oscillation, the period of oscillation, and guaranteed convergence rate can be correctly estimated. Finally, two numerical examples are provided to illustrate the use of the main result.
