Abstract
This chapter is on analyzing nonlinear dynamic systems with employment of Periodicity Ratio and a statistic hypothesis. By introducing the statistical hypothesis, the efficiency and accuracy of diagnosing the nonlinear characteristics of dynamic systems are improved. A new approach of accurately determining the Periodicity Ratio is developed. Overlapping points in a Poincare map are verified on a statistically sound basis. The characteristics of nonlinear systems are investigated by using the present approach. The numerical results generated by the approach are compared with those of the conventional approaches. The distinguished advantages of the approach are presented.
