Research on Optimal Strategy of Cyclists Based on Curve Fitting and Hamiltonian Function

In this paper, the power curve is first fitted by the power function, and the PC model is established. Then, six indexes are selected to establish the PP model, and the radar chart is used to reflect the rider's ability. It is regarded as an optimal control problem. First of all, the relationship between power and speed is obtained through force analysis. Then, according to Pontriagin's maximum principle, the Hamiltonian function is obtained. We predict that the shortest time of the Tokyo Olympic Games in 2021 is 52 minutes by solving this function.
