This paper presents a highly accurate algorithm,based on precise integration method（PIM）,to investigate the aeroelastic system of an airfoil with control surface.The nonlinear system is separated as linear sub-systems,which are solved by PIM stepwise.During each step,a predictor-corrector algorithm is proposed to detect switching points between sub-systems.Numerical examples show that,the presented algorithm is much more accurate and efficient than the widely-used Runge-Kutta method.Sometimes,the Runge-Kutta method even provides false results.With such high precision and efficiency,the presented algorithm has the potential to become a benchmark for comparison in solving piecewise-smooth dynamical systems.
