EXISTENCE AND CONSTRUCTION OF A PERIODIC SOLUTION OF AUTONOMOUS DYNAMICAL SYSTEMS
Keywords:
periodic solution, existence of a solution, integral equation, minimizing sequences, optimal control.Abstract
A new method for investigating periodic solutions of autonomous dynamical systems described by ordinary differential equations is proposed. Necessary and sufficient conditions for the existence of a periodic solution are obtained and an algorithm for constructing a periodic solution based on the limit points of minimizing sequences is developed. By introducing a control function, the original problem is reduced to the Fredholm integral equation of the first kind. Based on the construction of a general solution of the Fredholm integral equation of the first kind, the construction of a periodic solution is reduced to solving a special initial optimal control problem.References
